SN74CB3Q3253 Datasheet (Texas Instruments) - Low-Voltage High-Bandwidth Bus Switch

SN74CB3Q3253, Low-Voltage High-Bandwidth Bus Switch

The SN74CB3Q3253 device is a high-bandwidth FET bus switch using 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 switching on the
