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.

Notes:
1. The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design.
4. ΔRON = RON max. - RON min.
5. Flatness is defined as the difference between the maximum and minimum value of On-Resistance measured.
