ISL3150ERS-485/RS-422 Differential Transceiver | Interface | 4 | Active | The ISL315xE family of 5V powered RS-485/RS-422 transceivers features high output drive and high ESD protection. The devices withstand ±16. 5kV IEC61000-4- 2 ESD strikes without latch-up.

These devices possess less than 125μA bus input currents, thus constituting a true 1/8 unit load. The high output drive combined with the low bus input currents allows for connecting up to 512 transceivers on the same bus. The receiver inputs feature a full fail-safe design that turns the receiver outputs high when the bus inputs are open or shorted. The ISL315xE family includes half and full-duplex transceivers with active-high driver-enable pins and active-low receiver enable pins. These transceivers support data rates of 115kbps, 1Mbps, and 20Mbps. Their performance is characterized from -40°C to +85°C. |

ISL3158AE±16.5kV ESD (IEC61000-4-2) Protected, Large Output Swing, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceiver | Integrated Circuits (ICs) | 1 | Obsolete | The ISL3158AE is a BiCMOS, IEC61000 ESD protected, 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. Each driver output and receiver input is protected against ±16. 5kV ESD strikes without latch-up. The ISL3158AE transmitter delivers exceptional differential output voltages (2. 4V min), into the RS-485 required 54Ω load, for better noise immunity or to allow up to eight 120Ω terminations in "star" or other non-standard bus topologies. This device has very low bus currents (+125µA/-75µA), so it presents a true "1/8 unit load" to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters. Receiver (Rx) inputs feature a "Full Fail-Safe" design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven bus. Rx outputs feature high drive levels - typically 28mA @ VOL= 1V (to ease the design of optocoupled isolated interfaces). Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state until the power supply has stabilized, and the Tx outputs are fully short circuit protected. The ISL3158AE is a half duplex version. It multiplexes the Rx inputs and Tx outputs to allow transceivers with output disable functions in an 8 Ld package. |

ISL3159E±15kV ESD Protected, +125°C, 40Mbps, 5V, PROFIBUS, Full Fail-safe, RS-485/RS-422 Transceivers | Integrated Circuits (ICs) | 9 | Active | The ISL3159E is a ±15kV IEC61000 ESD protected, 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. It also features the larger output voltage and higher data rate (up to 40Mbps) required by high speed PROFIBUS applications, and is offered in industrial and extended Industrial (-40°C to +125°C) temperature ranges. The low bus currents (+220µA/-150µA) present a "1/5 unit load" to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specification’s load limit and without using repeaters. This transceiver requires a 5V ±10% tolerance supply, and delivers at least a 2. 1V differential output voltage over this supply range. This translates into better noise immunity (data integrity), longer reach, or the ability to drive up to six 120Ω terminations in "star" or other nonstandard bus topologies, at the exceptional 40Mbps data rate. SCSI applications benefit from the ISL3159’s low receiver and transmitter part-to-part skews. The ISL3159 is perfect for high speed parallel applications requiring simultaneous capture of large numbers of bits. The low bit-to-bit skew eases the timing constraints on the data latching signal. Receiver (Rx) inputs feature a "full fail-safe" design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. Rx outputs feature high drive levels (typically >30mA at VOL= 1V) to ease the design of optically isolated interfaces. Hot plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes. Driver (Tx) outputs are short-circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive. |

ISL3170E±15kV ESD Protected, 3.3V, Full Fail-Safe, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers | Interface | 2 | Active | The Renesas ISL317xE are ±15kV IEC61000 ESD protected, 3. 3V powered single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125µA/-100µA), so they present a true "1/8 unit load" to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification's 32 unit load maximum, and without using repeaters. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator using an RS-485 network, so the high allowed node count minimizes the number of repeaters required. Receiver (Rx) inputs feature a "Full Fail-Safe" design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes. The ISL3170E through ISL3175E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Slew rate limited versions also include receiver input filtering to enhance noise immunity in the presence of slow input signals. The ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E, and ISL3177E are configured for full duplex (separate Rx input and Tx output pins) applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 Ld packages. |
