MAX4820ETP+

The MAX4820ETP+ is an 8-channel, cascadable relay driver with serial interface in 20 pin TQFN package. It offer built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays. Device is especially useful when driving +3V relays. Each independent open-drain output features a 2ohm on-resistance and sink 70mA (min) of load current, it consume less than 50µA (max) quiescent current and have 1µA output off-leakage current. Built-in hysteresis (schmitt trigger) on all digital inputs allows this device to be used with slow rising and falling signals from optocouplers or RC power-up initialization circuits. It is used in central office, ATE, DSL, ADSL line cards and E1/T1 redundancy.
