MAX4545Quad/Dual, Low-Voltage, Bidirectional RF/Video Switches | Analog Switches - Special Purpose | 14 | Active | The MAX4545/MAX4546/MAX4547 are low-voltage T-switches designed for switching RF and video signals from DC to 300MHz in 50Ω and 75Ω systems. The MAX4545 contains four normally open single-pole/single-throw (SPST) switches. The MAX4546 contains two dual SPST switches (one normally open, one normally closed.) The MAX4547 contains two single-pole/double-throw (SPDT) switches.Each switch is constructed in a "T"configuration, ensuring excellent high-frequency off isolation and crosstalk of -80dB at 10MHz. They can handle rail-to-rail analog signals in either direction. On-resistance (20Ω max) is matched between switches to 1Ω max and is flat (0.5Ω max) over the specified signal range, using ±5V supplies. The off leakage current is less than 5nA at +25°C and 50nA at +85°C.These CMOS switches can operate with dual power supplies ranging from ±2.7V to ±6V or a single supply between +2.7V and +12V. All digital inputs have 0.8V/2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using ±5V or a single +5V supply.ApplicationsAutomated Test Equipment (ATE)High-Speed Data AcquisitionNetworkingRF SwitchingTest EquipmentVideo Signal Routing |

MAX4548Serially Controlled, Triple 3x2 Audio/Video Crosspoint Switches | Interface | 3 | Obsolete | The MAX4548/MAX4549 serial-interface, programmable, triple 3x2 audio/video crosspoint switches are ideal for multimedia applications. The devices include three crosspoint switch matrices, each containing three inputs and two outputs. To improve off-isolation, each switch matrix has a shunt input and each output is selectively programmable for clickless or regular-mode operation. A selectable set of internal resistive voltage dividers supplies DC bias for each output when using AC-coupled inputs. To improve crosstalk, the voltage dividers include four externally accessible bypass points.The MAX4548/MAX4549 feature 35Ω max on-resistance, 7Ω on-resistance matching between channels, 5Ω on-resistance flatness, and 0.07% total harmonic distortion (THD). Additionally, they feature off-isolation of -85dB at 20kHz and -72dB at 10MHz, with crosstalk of -85dB at 20kHz and -55dB at 10MHz. The MAX4548 uses a 2-wire I²-compatible serial interface, while the MAX4549 uses a 3-wire SPI™/QSPI™/MICROWIRE™-compatible serial interface. These parts are available in 36-pin SSOP packages and are specified for the extended (-40°C to +85°C) operating range.ApplicationsHigh-End Audio SystemsPC Multimedia BoardsSecurity SystemsSet-Top BoxesVideo Conferencing Systems |

MAX4552±15kV ESD-Protected, Quad, Low-Voltage, SPST Analog Switches | Interface | 11 | Active | The MAX4551/MAX4552/MAX4553 are quad, low-voltage, single-pole/single-throw (SPST) analog switches. Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage. On-resistance (100Ωmax) is matched between switches to 4Ω max, and is flat (8Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C.The MAX4551 has four normally closed (NC) switches, and the MAX4552 has four normally open (NO) switches. The MAX4553 has two NC and two NO switches.These CMOS switches can operate with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. They are fully specified for single +2.7V operation.All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply.ApplicationsAudio-Signal RoutingAvionicsBattery-Powered ApplicationsData AcquisitionNetworkingTest Equipment |
