STMicroelectronics M74HCT138B1R is a high-speed CMOS 1-of-8 decoder/demultiplexer from the 74HCT series. This device features one independent 1-of-8 decoding circuit. It accepts three binary select inputs (A, B, C) and provides eight mutually exclusive active-low outputs. The decoder is enabled by three select inputs (G1, G2A, G2B), with G1 being active high and G2A/G2B being active low. This functionality makes it suitable for address decoding, data routing, and memory selection applications. The M74HCT138B1R operates from a single 4.5V to 5.5V supply and offers a current drive capability of 4mA for both high and low outputs. It is housed in a 16-pin dual in-line package (DIP) for through-hole mounting, with a standard 16-DIP (0.300", 7.62mm) footprint. The operating temperature range is -55°C to 125°C. This component finds application in industrial automation, consumer electronics, and communication systems.
