SN74CB3Q3244 Datasheet (Texas Instruments)

SN74CB3Q3244, 8-BIT FET BUS SWITCH

ordering information The SN74CB3Q3244 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (ron).

The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail
