74CB3Q3257-Q100
74CB3Q3257-Q100 is 4-bit 1-of-2 FET multiplexer/demultiplexer manufactured by Nexperia.
description
The 74CB3Q3257-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3) and is suitable for use in automotive applications.
