Texas Instruments 20-SOIC SN74ALS638A-1DWRG4

The SN74ALS638A-1DWRG4 is a quad 2-input multiplexer in a small-outline, dual-row surface-mount package. Manufactured by Texas Instruments, this digital integrated circuit (IC) belongs to the 74ALS logic family and features low power consumption with Schottky diodes for high-speed operation. It selects one of four data inputs and routes it to a common output based on the values of two control signals. The device operates with a wide range of supply voltages and is suitable for communication and general-purpose logic applications where space-saving and fast switching are essential.
