Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SN74CB3Q3253PWRG4

The SN74CB3Q3253PWRG4 is a dual 1-of-4 FET multiplexer-demultiplexer designed for low-voltage, high-bandwidth applications. It operates within a voltage range of 2.3 V to 3.6 V and supports rail-to-rail switching for data I/O ports, accommodating signal levels from 0 V to 5 V. The device features a high bandwidth data path capable of handling frequencies up to 500 MHz, with a typical ON-state resistance of 4,Ѷ, ensuring minimal propagation delay. It includes bidirectional data flow with low input/output capacitance, which helps reduce loading and signal distortion. The device is equipped with output enable pins that are active-low, and it supports partial power-down mode operation. ESD protection is robust, rated at 2000 V for the human body model and 1000 V for the charged device model. The SN74CB3Q3253PWRG4 is suitable for both digital and analog applications, including USB interfaces and video communications systems.
