FST3244 — 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 FST3244 switch provides eight-bits of high-speed,
CMOS, TTL-compatible bus switching in a standard ’244
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 two four-bit switches with
separate /OE inputs. 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.
