The MAX4571–MAX4574 serial-interface controlled switches are ideal for multimedia applications. Each device features 35Ω max on-resistance, -90dB audio off-isolation at 20kHz, -60dB video off-isolation at 1.0MHz, and "clickless" mode operation for audio applications.The MAX4571/MAX4573 contain eleven SPST switches, while the MAX4572/MAX4574 contain two SPST switches and six SPDT switches. The MAX4571/MAX4572 feature a 2-wire, I2C-compatible serial interface. The MAX4573/MAX4574 feature a 3-wire, SPI™/QSPI™/MICROWIRE™-compatible serial interface. All four parts are available in 28-pin QSOP, SSOP, and wide SO packages and operate over the commercial and extended temperature ranges.ApplicationsAudio SystemsPC Multimedia BoardsSet-Top BoxesVideo Conferencing Systems

The MAX4575/MAX4576/MAX4577 are low-voltage, high electrostatic discharge (ESD)-protected, dual single-pole/single-throw (SPST) analog switches. The normally closed (NC) and normally open (NO) pins are protected against ±15kV ESD without latchup or damage. Each switch can handle rail-to-rail analog signals. Off-leakage current is 0.5nA at +25°C. These analog switches are suitable for low-distortion audio applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements (0.5µW), require less board space, and are more reliable than mechanical relays. Each device is controlled by TTL/CMOS input voltage levels and is bilateral.These switches feature guaranteed operation from a single supply of +2V to +12V, making them ideal for use in battery-powered applications. On-resistance is 70Ω (max), matched between switches to 0.5Ω (typ) and flat (2Ω typ) over the specified signal range.The MAX4575 has two NO switches, the MAX4576 has two NC switches, and the MAX4577 has one NO and one NC switch. These devices are available in 8-pin µMAX® and SO packages.ApplicationsCell PhonesDigital Still CamerasDigital Television (Receivers, Set-Top Boxes)Palmtop ComputersPDAs

The MAX4588 low-voltage, dual 4-channel multiplexer is designed for RF and video signal processing at frequencies up to 180MHz in 50Ω and 75Ω systems. A flexible digital interface allows control of on-chip functions through either a parallel interface or an SPI™/MICROWIRE™ serial port.Each channel of the MAX4588 is designed using a "T" switch configuration, ensuring excellent high-frequency off-isolation. The MAX4588 has low on-resistance of 60Ω max, with an on-resistance match across all channels of 4Ω max. Additionally, on-resistance is flat across the specified signal range (2Ω max). The off- leakage current is under 1nA at TA= +25°C, and less than 10nA at TA= +85°C.The MAX4588 operates from single +2.7V to +12V or dual ±2.7V to ±6V supplies. When operating with a +5V supply, the inputs maintain TTL- and CMOS-level compatibility. The MAX4588 is available in 28-pin narrow DIP, wide SO, and space-saving SSOP packages.ApplicationsAutomated Test Equipment (ATE)High-Speed Data AcquisitionNetworkingRF SwitchingVideo Signal Routing

The MAX4580/MAX4590/MAX4600 dual analog switches feature low on-resistance of 1.25Ω max. On-resistance is matched between switches to 0.25Ω max and is flat (0.3Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.The MAX4580 has two NC (normally closed) switches, the MAX4590 has two NO (normally open) switches, and the MAX4600 has one NC (normally closed) and one NO (normally open) switch.These switches operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +12V single supply or ±15V dual supplies.ApplicationsCommunication SystemsPBX/PABX SystemsReed Relay ReplacementTest Equipment
