Texas Instruments 20-SOIC SN74BCT640DW

The SN74BCT640DW is a TI (Texas Instruments) manufactured IC, belonging to the 74BCT logic family. It is a quadruple 2-input multiplexer with individual control inputs, designed for low power consumption and high-speed operation. The device allows data selection from four sources based on two select lines and routes the chosen input to a common output. DIP, SOIC or alternative packages are typical for this part, suitable for both through-hole and SMD assembly. Detailed specifications including pinout, electrical characteristics, and application circuits can be found in its datasheet available from TI or authorized distributors.
