Detailed Description
The MAX4820/MAX4821 8-channel relay drivers offer
built-in kickback protection and drive +3.3V/+5V non-
latching or dual-coil-latching relays. These devices are
especially useful when driving +3V relays. Each inde-
pendent open-drain output features a 2 Ω on-resistance
and is guaranteed to sink 70mA (min) load current. Both
devices consume less than 50μA (max) quiescent cur-
rent and feature 1μA (min) output off-leakage current.
The MAX4820 features an SPI/QSPI/MICROWIRE-com-
patible serial interface. Input data is shifted into an 8-bit
shift register and latched to the outputs when CS transi-
tions from low to high. Each data bit in the shift register
corresponds to a specific output, allowing independent
control of all outputs.

The MAX4821 features a 4-bit (A0, A1, A2, LVL) parallel
input interface. The three bits (A0, A1, A2) determine
the output address, and LVL determines whether the
selected output is switched on or off. Data is latched to
the outputs when CS transitions from low to high.
Both devices feature separate set and reset functions
that allow the user to turn on or turn off all outputs
simultaneously with a single control line. Built-in hys-
teresis (Schmidt trigger) on all digital inputs allows this
device to be used with slow rising and falling signals,
such as those from optocouplers or RC power-up ini-
tialization circuits. The MAX4820/MAX4821 are avail-
able in 20-pin TSSOP and space-saving 20-pin Thin
QFN packages.
