ISL4485E5V, Half Duplex, 20Mbps, ±15kV ESD Protected, RS-485/RS-422 Transceiver | Integrated Circuits (ICs) | 3 | Obsolete | The Intersil ISL4485E is a high speed, BiCMOS 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this Intersil device is specified for 10% tolerance supplies (4. 5V to 5. 5V). The excellent differential output voltage coupled with high drive-current output stages allow 20Mbps operation over twisted pair networks up to 450 feet in length. The 25kΩ receiver input resistance presents a single unit load to the RS-485 bus, allowing up to 32 transceivers on the network. Receiver (Rx) inputs feature a fail-safe if open design, which ensures a logic high Rx output if Rx inputs are floating. 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. The half duplex configuration multiplexes the Rx inputs and Tx outputs to allow transceivers with Rx and Tx disable functions in 8 lead packages. |
ISL44865V, Half Duplex, 40Mbps,RS-485/RS-422 Transceiver | Integrated Circuits (ICs) | 2 | Obsolete | The Intersil ISL4486 and ISL81486 are BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication, and feature the larger output voltage and higher data rate - up to 40Mbps - required by high speed PROFIBUS applications. Unlike competitive products, these Intersil devices are specified for 10% tolerance supplies (4. 5V to 5. 5V) and deliver at least a 2. 3V differential output voltage over this supply range. At the 5% tolerance specified by many competitors, the ISL4486 delivers an unsurpassed 2. 5V differential signal into a 54Ω total load. This translates into longer reach, or better data integrity, at the exceptional 40Mbps data rate. SCSI applications benefit from the ISL4486's low receiver and transmitter part-to-part skews, which make it perfect for high speed parallel applications where large numbers of bits must be simultaneously captured. The low bit-to-bit skew eases the timing constraints on the data latching signal. These devices present a 0. 6 unit load to the RS-485 bus, which allows up to 50 transceivers on the network. Receiver (Rx) inputs feature a fail-safe if open design, which ensures a logic high Rx output if Rx inputs are floating. 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. |
ISL4489E5V, Full Duplex, 250kbps Slew Rate Limited With Enable, ±15kV ESD Protected, RS-485/RS-422 Transceiver | Integrated Circuits (ICs) | 4 | Active | The ISL4489E and ISL4491E are ESD protected, "fractional"Unit Load (UL), BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output and receiver input is protected against ±15kV ESD strikes without latch-up. Unlike competitive versions, these devices are specified for 10% tolerance supplies (4. 5V to 5. 5V). The Rx inputs and Tx outputs present a 1/8 unit load to the RS-485 bus, which allows a total of 256 transmitters and receivers on the network for large node count systems. These devices are configured for full duplex (separate Rx input and Tx output pins) applications, so they are ideal for RS-422 networks requiring high ESD tolerance on the bus pins. The ISL4489E uses a slew rate limited driver that reduces EMI and minimizes reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Data rates up to 15Mbps are achievable using the ISL4491E, which features higher slew rates. The receiver (Rx) inputs feature a "fail-safe if open" design, which ensures a logic high Rx output if Rx inputs are floating. The 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. |
