Functions
The MAX4820/MAX4821 feature set and reset inputs that
allow the user to simultaneously turn all outputs on or off
using a single control line. Drive
SET
low to set all latch-
es and registers to 1 and turn all outputs on.
SET
over-
rides all serial/parallel control inputs. Drive
RESET
low to
clear all latches and registers and turn all outputs off.
RESET
overrides all other inputs, including
SET
.
Applications Information
Daisy Chaining
The MAX4820 features a digital output, DOUT, that pro-
vides a simple way to daisy chain multiple devices. This
feature allows the user to drive large banks of relays
using only a single serial interface. To daisy chain multi-
ple devices, connect all
CS
pins together, and connect
the DOUT of one device to the DIN of another device
(see Figure 3). During operation, a stream of serial data
is shifted through all the MAX4820s in series. When
CS
goes high, all outputs update simultaneously.
The MAX4820 can also be used in a slave configuration
that allows the user to address individual devices.
Connect all the DIN pins together, and use the
CS
input
to address one device at a time. Drive
CS
low to select
a slave and input the data into the shift register. Drive
CS
high to latch the data and turn on the appropriate
outputs. Typically, in this configuration only one slave is
addressed at a time.
