RESET
Reset Input. Drive

low to clear all latches and registers (all outputs
are turned off).
RESET
overrides all other inputs. If
RESET
and

are pulled
low at the same time, then
RESET
takes precedence.

CS
Chip-Select Input.
MAX4820:
Drive
CS
low to select the device. When
CS
is low, data at DIN is
clocked into the 8-bit shift register on SCLK
’
s rising edge. Drive
CS
from low
to high to latch the data to the registers and activate the appropriate relays.
MAX4821:
Drive
CS
low to select the device and set level on LVL. Drive
CS
from low to high to latch the address and level data to the output.

DOUT
Serial Data Output. DOUT is the output of the 8-bit shift register. This output
can be used to daisy chain multiple MAX4820s. The data at DOUT appears
synchronous to SCLK
