FSTU32160

16-Bit to 32-Bit Multiplexer/Demultiplexer Bus Switch

with −2V Undershoot Protection

General Description

Features

■ Undershoot hardened to −2V (A and B Ports).

■ Slower Output Enable times prevent signal disruption

■ 4Ω switch connection between two ports.

The Fairchild Switch FSTU32160 is a 16-bit to 32-bit high-

speed CMOS TTL-compatible multiplexer/demultiplexer

bus switch. The low on resistance of the switch allows

inputs to be connected to outputs without adding propaga-

tion delay or generating additional ground bounce noise.

■ Minimal propagation delay through the switch.

■ Low l_CC

The device can be used in applications where two buses

need to be addressed simultaneously. The FSTU32160 is

designed so that the A Port demultiplexes into B₁or B₂or

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

■ See Applications Note AN-5008 for details

both. The A and B Ports are “undershoot hardened” with

UHC protection to support an extended range to 2.0V

below ground. Fairchild’s integrated Undershoot Hardened

Circuit, UHC senses undershoot at the I/O’s, and responds

by preventing voltage differentials from developing and

turning on the switch.

Two select (SEL₁, SEL₂) inputs provide switch enable con-

trol. When SEL₁, SEL₂are HIGH, the device precharges

the B Port to a selectable bias voltage (Bias V) to minimize

live insertion noise.
