PC74HCT138N Integrated Circuit 16Pin
Description:
The PC74HCT138N is a high-speed CMOS 3-to-8 line decoder/demultiplexer with active-low outputs, designed by Philips (now NXP Semiconductors). It’s TTL-compatible and ideal for memory address decoding, data routing, and logic-level control in microprocessor systems. With three binary inputs and three enable inputs, it can selectively activate one of eight outputs—making it a versatile tool for expanding addressable I/O or memory space.
