FST3244: 8-Bit Bus Switch

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.

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.
