+3.
3V/+5V, 8-Channel, Cascadable Relay Drivers with Serial/Parallel Interface
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 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™-/MICROWIRE™compatible serial interface.
Input data is shifted into an 8bit shift register and latched to the outputs when CS...
