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.
The device is organized as a 20-bit bus switch. When OE
X
is LOW, the switch is ON and Port A is connected to Port B.
When OE
X
is HIGH, a high impedance state exists
between the A and B Ports.
