The MC74HC138AD from ON Semiconductor is a high-performance silicon-gate CMOS 1-of-8 decoder/demultiplexer. This device decodes a three-bit address to one of eight active-low outputs. It features three chip select inputs, two active-low and one active-high, which facilitate demultiplexing, cascading, and chip-selecting functions.
The MC74HC138AD operates over a wide voltage range of 2.0V to 6.0V, making it suitable for various applications. Its outputs can directly interface with CMOS, NMOS, and TTL logic levels, and it offers an output drive capability of 10 LSTTL loads. The device is designed for surface mounting and comes in a standard 16-SOIC package.
With a broad operating temperature range of -55°C to 125°C, this decoder/demultiplexer is robust for demanding environments. It features low input current and high noise immunity characteristic of CMOS devices. The MC74HC138AD is also Pb-free and halogen-free, complying with RoHS standards.
