General Description

The ON Semiconductor Switch FSTU32160 is a 16−bit to 32−bit

highspeed 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.

CASE 948BR

CONNECTION DIAGRAM

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 B or B or both. The A and B Ports have

“undershoot hardened” circuit protection to support an extended range

to 2.0 V below ground. The integrated Undershoot Hardened Circuit

senses undershoot at the I/O’s, and responds by preventing voltage

differentials from developing and turning on the switch.

Two select (S , S ) inputs provide switch enable control. When S ,

S are HIGH, the device precharges the B Port to a selectable bias

voltage (Bias V) to minimize live insertion noise.

Features

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

• Slower Output Enable Times prevent Signal Disruption

• 4 W Switch Connection between Two Ports

• Minimal Propagation Delay through the Switch

• Low I

• Zero Bounce in Flow−through Mode

• Control Inputs Compatible with TTL Level

• See Application Note AN−5008 for Details

• This Device is Pb−Free and is RoHS Compliant
