FST3245 — 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 FST3245 switch provides eight-bits of high-speed
CMOS TTL-compatible bus switching in a standard ’245
pin-out. The low on resistance 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. When
/OE is LOW, the switch is ON and port A is connected to
port B. When /OE is HIGH, the switch is OPEN and a
high-impedance state exists between the two ports.
