FST3257MX Datasheet PDF - ON Semiconductor

●The FST3257MX is a 2:1 quad CMOS multiplexer/demultiplexer Bus Switch provides TTL-compatibility. The low on-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. When OE\ is low, the select pin connects the A port to the selected B port output. When OE\ is high, the switch is open and a high-impedance state exists between the two ports.

● Minimal propagation delay through the switch

● Low ICC

● Zero bounce in flow-through mode

● Control inputs compatible with TTL level

● 4R Switch connection between two ports
