Dual 4:1 Multiplexer/Demultiplexer Bus Switch

with −2V Undershoot Protection

General Description

Features

The Fairchild Switch FSTU3253 is a dual 4:1 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 propagation

delay or generating additional ground bounce noise.

■ Undershoot hardened to −2.0V

■ 4Ω switch connection between two ports

■ Minimal propagation delay through the switch

■ Low l_CC

■ Zero bounce in flow-through mode

When OE is LOW, S₀and S₁connect the A Port to the

■ Control inputs compatible with TTL level

selected B Port output. When OE is HIGH, the switch is

OPEN and a high-impedance state exists between the two

ports.

■ See application note AN-5008 and AN-5021 for details

on undershoot

The A and B Ports are protected against undershoot to

support an extended range to 2.0V below ground.

Fairchild’s integrated Undershoot Hardened Circuit

(UHC ) senses undershoot at the I/O and responds by

preventing voltage differentials from developing and turn-

ing the switch on.
