The Texas Instruments SN74LV4051ATPWRQ1 is an automotive-qualified 8:1 single-channel general-purpose analog multiplexer and demultiplexer in a 16-pin TSSOP package. It operates from a 2 V to 5.5 V supply, handles eight input channels routed to one output, and is rated for -40°C to 105°C. The SN74LV4051ATPWRQ1 has a 180 ohm drain-to-source resistance, roughly 7 ns propagation delay, and draws about 20 microamps of operating supply current.

Analog multiplexers expand a single ADC input or DAC output to serve many signals, letting one converter sample eight sensors in sequence instead of requiring eight converters. Because the switch path is bidirectional, the same device also works as a demultiplexer to steer one source to eight destinations. The automotive-qualified grade and -40°C to 105°C rating make the SN74LV4051ATPWRQ1 suitable for in-vehicle body electronics, sensor interfaces, and instrument clusters, as well as industrial data acquisition. Automotive tier-one suppliers and industrial OEM design teams are the typical purchasers.
