74CB3Q3253 & 74CB3Q3257 FET Bus Switches

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