Nexperia 74CB3Q3253 & 74CB3Q3257 are low-delay high-bandwidth bus switches with an integrated charge pump. These dual and quad high-bandwidth single-pole, quad-throw FET Bus switches are suitable for memory interleaving, sensor multiplexing, signal gating and other switching applications. 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.
