Product Summary

The MAX4820 is a +3.3V/+5V, 8-Channel, Cascadable Relay Driver with Serial/Parallel Interface. The MAX4820 offers built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays. The MAX4820 is especially useful when driving +3V relays. Each independent open-drain output features a 2Ω on-resistance and is guaranteed to sink 70mA (min) of load current. Both devices consume less than 50μA (max) quiescent current and have 1μA output off-leakage current. The applications of the MAX4820 include Central Office, ATE, DSL, ADSL Line Cards, Industrial Equipment, E1/T1 Redundancy.
