Texas Instruments SN74CB3Q3253 Dual 1-of-4 FET Multiplexer/Demultiplexer 2.5-V/3.3-V Low-Voltage High-Bandwidth Bus Switch 74CB3Q3253DBQRE4

The SN74CB3Q3253 is a dual 1-of-4 FET multiplexer/demultiplexer designed for low-voltage applications, operating at 2.5-V to 3.3-V. It features a high-bandwidth data path capable of handling frequencies up to 500 MHz and supports rail-to-rail switching on data I/O ports. The device has a low ON-state resistance of approximately 4,Ѷ, which minimizes propagation delay and signal distortion. It is bidirectional and allows for near-zero propagation delay, making it suitable for high-speed data applications. The SN74CB3Q3253 is 5-V tolerant on its I/Os, enabling compatibility with a range of signal levels from 0 to 5 V. It operates with low power consumption, drawing about 0.6 mA typically. The device also includes features such as undershoot clamp diodes on data and control inputs, partial power-down mode operation, and robust ESD performance, tested to 2000-V HBM and 1000-V CDM standards. It is available in multiple package options, including SSOP, TVSOP, and TSSOP, making it versatile for various design requirements. Applications include video broadcasting and communications systems.
