Overview
The TS3V340RGYR from Texas Instruments is a 4-channel, 2:1 (SPDT) video switch designed for high-bandwidth video applications. This device features a single switch-enable input and a select input that controls the data path of the multiplexer/demultiplexer. It is particularly suited for composite and RGB video switching due to its low differential gain and phase, wide bandwidth, and low crosstalk. The TS3V340RGYR operates within a supply voltage range of 3 V to 3.6 V and is packaged in a 16-pin VQFN (RGY) package with an exposed pad.
