FST16862

20-Bit Bus Switch

General Description

The Fairchild Switch FST16862 provides 20-bits of high-

speed CMOS TTL-compatible bus switching. The low On

Resistance of the switch allows inputs to be connected to

outputs without adding propagation delay or generating

additional ground bounce noise.

is LOW, the switch is ON and Port A is connected to Port B.

between the A and B Ports.
