Selecting one of several memory chips, peripherals, or output lines from just a few microcontroller pins is exactly the job a 3-to-8 decoder is built for, taking a 3-bit binary input and activating exactly one of its 8 outputs at a time. This genuine Nexperia 74HC138 brings that address-decoding and device-selection function to a SOIC-16 surface-mount chip, built for a finished PCB design.
