8-Bit Bus Switch
General Description
The Fairchild Switch FST3345 provides 8-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 an 8-bit switch bank with dual
output enable inputs (OE and OE). When OE is LOW or
OE is HIGH, the switch is ON and Port A is connected to
Port B. When OE is HIGH and OE is LOW, the switch is
OPEN and a high-impedance state exists between the two
ports.
