TS4100/01/02 Data Sheet
"Rail-to-Rail Plus"™, 1% RON Flatness, 0.8 V to 5.25 V Analog
Switches/Multiplexers
The TS410x family of analog switches and multiplexers consists of the TS4100 8-chan-
nel analog multiplexer, the TS4101 dual 4-channel analog multiplexer, and the TS4102
triple single-pole/double-throw (SPDT) switch. These switches are unique because they
can operate at supply voltages as low as 0.8 V while accepting input signal swings
above the supply voltage up to 5.25 V ("Rail-to-Rail Plus"™). The on-resistance variation
over the entire signal swing range is less than 1%, exhibiting excellent linearity and con-
sistency in dynamic and measurement applications. With a supply current of only 675
nA, the TS4100-TS4102 family input and output leakage is less than 0.5 nA, both when
off and when on.
The TS4100-TS4102 are fully specified over the –40 °C to +85 °C temperature range
and is available in a low-profile, thermally-enhanced 16-pin 3.3 mm TQFN package with
an exposed back-side paddle. For best performance, solder exposed back-side paddle
to PCB ground.
