Features

Description

•

CMOS Technology for Bus and Analog Applications

Pericom Semiconductors PI5A4763 is a dual 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, 1.65V to 5.5V, the

PI5A4763 has a low On-Resistance of 0.6Ω @ 2.7V.

Low On-Resistance: 0.6Ω @ 2.7V

Wide V Range: 1.65V to 5.5V

Rail-to-Rail Signal Range

Control Input Overvoltage Tolerance: 5.5V min.

Fast Transition Speed: TBD

High Off Isolation: TBD

The control input, IN , tolerates input drive signals up to 6.0V,

independent of supply voltage.

Crosstalk Rejection Reduces Signal Distortion: TBD

tive terminal of the comparator (CMP-) is less than the threshold

Extended Industrial Temperature Range: –40°C to 85°C

(internally set to V /3), CMP0 (comparator output) is a logic

high. A logic low on CMP0 occurs when CMP- rises above the

threshold.
