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 4Ω at 1.8V, 2.4Ω at 2.3V & 1Ω 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.

by internal diodes. Limit forward diode current to 30mA.
Caution:
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of
this specification is not implied.
