1 Low-Voltage
SPDT Analog Switch
Description
The PI5A3159 is a high-bandwidth, fast single-pole double-throw
(SPDT) CMOS switch. It can be used as an analog switch or as
a low-delay bus switch. Specified over a wide operating power
supply voltage range, 1.8V to 5.5V, the PI5A3159 has a maximum
On-Resistance of 4 at 1.8V, 2.4 at 2.3V & 1 at 4.5V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
Control input, S, tolerates input drive signals up to 5.5V, inde-
pendent of supply voltage.
PI5A3159 is a low On-Resistance replacement for the PI5A3157
and NC7SB3157.

Notes:
1. This product has always shipped as only a lead free product, but since it was introduced prior to Pericom's strategy of adding an E to all Green/
Lead free parts many customers order it without the E suffix. Please migrate new designs and qualification to include the E suffix. Pericom at
this point in time will continue to offer devices marked both ways, but may at a later date eliminate the non-E part number.
2. Thermal Characteristics can be found on the world wide web at www.pericom.com/packaging/
