The MAX14802/MAX14803/MAX14803A digital inter-
face inputs CLK, DIN, LE, and CLR operate on the V
supply voltage.
Digital output DOUT is provided to allow the connection
of multiple MAX14802/MAX14803/MAX14803A devices
by daisy-chaining (Figure 3). Connect each DOUT to the
DIN of the subsequent device in the chain. Connect CLK,

to update all devices simultaneously. Drive CLR high to
open all the switches simultaneously. Additional shift reg-
isters can be included anywhere in series with the
MAX14802/MAX14803/MAX14803A data chain.
The MAX14802/MAX14803/MAX14803A do not require
special sequencing of the V
voltages; however, analog switch inputs must be
unconnected, or satisfy V
during power-up and power-down. Bypass V
and V
close as possible to the device.
