74CB3Q3257PW

4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump

The 74CB3Q3257 is a quad high-bandwidth single-pole, double-throw FET bus switch.The device features one select input (S) and one output enable input (OE). The switch is disabled when the OE input is HIGH. An internal charge-pump increases the gate voltage of the NMOS pass transistor. The result is improved RON and RON(flat) performance and the ability to switch 5 V signals when VCC = 3.3 V.
