1 / 9 page March 2008 ©1997 Fairchild Semiconductor Corporation www.fairchildsemi.com FST3245 • Rev. 1.0.2 FST3245 — 8-Bit Bus Switch Features 4 Ω Switch Connection between Two Ports Minimal Propagation Delay through the Switch Low ICC 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.
