FST3345: 8-Bit Bus Switch

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.

Features

• 4ohm switch connection between two ports.
• Minimal propagation delay through the switch.
• Low l_CC.
• Zero bounce in flow-through mode.
• Control inputs compatible with TTL level.
