Product Overview

The MAX4821ETP+ is an 8-channel, cascadable relay driver with parallel 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.
  • Supply voltage range is 2.3V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • 8 independent output channels
  • Parallel 4bit interface
  • SET(complementary) function to turn on all outputs simultaneously
  • RESET (complementary) function to turn off all outputs simultaneously
  • Turn-on time and turn-off time of 1µs
  • Thermal shutdown of 160°C
  • LVL setup time is 100ns
