TS3V340

The Texas Instruments TS3V340 is a versatile 4-bit 1-of-2 multiplexer/demultiplexer, functioning as a 4-channel 2:1 SPDT video switch. It is engineered for applications requiring high-quality video signal routing, including composite and RGB video.

Key electrical characteristics include a wide bandwidth of 500 MHz, low crosstalk of -80 dB, and low differential gain and phase distortion (0.2% DG, 0.1° DP typical). The device features low and flat ON-state resistance, typically 3 Ohms, with flatness of 1 Ohm. It operates over a VCC range of 3 V to 3.6 V and supports bidirectional data flow with near-zero propagation delay.

For signal integrity, the TS3V340 includes undershoot clamp diodes on data and control inputs. It also supports partial power-down mode operation via the Ioff feature. The switch is designed to meet stringent reliability standards, with latch-up performance exceeding 100 mA per JESD 78, Class II, and ESD performance tested to 2000-V HBM and 1000-V CDM.

The TS3V340 is available in various surface-mount packages, including SOIC, TSSOP, TVSOP, SSOP, and VQFN. Its robust specifications make it suitable for demanding video switching applications.
