FST3245
Features
- 4 Ω Switch Connection between Two Ports
- Minimal Propagation Delay through the Switch
- Low ICC
- Zero Bounce in Flow-through Mode
- Control Inputs patible with TTL Level
Description
The FST3245 switch provides eight-bits of high-speed CMOS TTL-patible 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.
