74CB3Q3257BQX

Nexperia 74CB3Q3253 & 74CB3Q3257 FET Bus Switches are dual and quad high-bandwidth single-pole, quad-throw FET Bus switches. The devices feature one select input (74CB3Q3257, S) or (74CB3Q3253, Sn) and one output enable input (74CB3Q3257, OE) or (74CB3Q3253, nOE). The switches are disabled when the OE or nOE 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 5V signals when VCC = 3.3V.
