MAX4821 Datasheet +3.3v/+5v / 8-channel / Cascadable Relay Drivers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2751; Rev 0; 1/03 +3.3V/+5V, 8-Channel, Cascadable Relay Drivers with Serial/Parallel.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX4820/MAX4821 8-channel relay drivers offer built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays.

These devices are especially useful when driving +3V relays.

Each independent open-drain output

Key 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 MAX4820 features an SPI™-/QSPI™-/.
