The Texas Instruments SN74CB3Q3257DBQR is a high-bandwidth, low-voltage FET bus switch designed for multiplexing and demultiplexing applications. This device features a 4-bit, 1-of-2 configuration, enabling flexible signal routing.
Key electrical characteristics include a high bandwidth of up to 500 MHz and a low, flat on-state resistance of typically 4 Ohms. It operates over a wide voltage range from 2.3V to 3.6V and supports 0- to 5V signaling levels on its data I/Os. The device also boasts low power consumption and 5V tolerant I/Os, making it suitable for various interfacing needs.
Designed for bidirectional data flow with near-zero propagation delay, the SN74CB3Q3257DBQR is ideal for applications such as USB interfaces, differential signal interfaces, bus isolation, and low-distortion signal gating. It supports both digital and analog signals.
The SN74CB3Q3257DBQR is supplied in a 16-pin SSOP package, designed for surface mounting. Its robust design includes undershoot clamp diodes on data and control inputs and meets stringent ESD performance standards.
