Specifications of MAX4800CTM+T

• Function: Switch
• Circuit: 8 x SPST - NO
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Package / Case: 48-WFQFN, Exposed Pad
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The MAX4800/MAX4801/MAX4802 digital interface
inputs CLK, DIN, LE, and CLR are tolerant of up to
+13.2V, independent of the V
ing compatibility with higher voltage controllers.
Digital output DOUT is provided to allow the connection
of multiple MAX4800/MAX4801/MAX4802 devices by
daisy chaining (Figure 3). Connect each DOUT to the
DIN of the subsequent device in the chain. Connect CLK,
LE, and CLR inputs of all devices, and drive LE logic-low
to update all devices simultaneously. Drive CLR high to
open all the switches simultaneously. Additional shift reg-
isters may be included anywhere in series with the
MAX4800/MAX4801/MAX4802 data chain.

The MAX4800/MAX4801/MAX4802 do not require spe-
cial sequencing of the V
ages; however, analog switch inputs must be
unconnected, or satisfy V
during power-up and power-down. Bypass V
and V
close to the device as possible.
