FST3345 — 8-Bit Bus Switch
Features
4 Ω Switch Connection between Two Ports
Minimal Propagation Delay through the Switch
Low I
CC
Zero Bounce in Flow-through Mode
Control Inputs Compatible with TTL Level
Description
The FST3345 switch provides eight-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 eight-bit switch 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.
