SN74CB3Q3305 Datasheet (Texas Instruments) - 2.5-V or 3.3-V Low-Voltage High-Bandwidth Bus Switch

SN74CB3Q3305, 2.5-V or 3.3-V Low-Voltage High-Bandwidth Bus Switch

The SN74CB3Q3305 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 switching input voltage beyon

SN74CB3Q3305 Features

* High-bandwidth data path (up to 500 MHz)1

* 5-V tolerant I/Os with device powered up or powered down

* Low and flat ON-state resistance (ron) characteristics over operating range (ron = 3 Ω typical)

* Supports input voltage beyond supply on data I/O ports
