MC74HCT138AD Description

Short technical summary and product information.

The MC74HCT138AD from ON Semiconductor is a high-performance silicon-gate CMOS 1-of-8 decoder/demultiplexer. It decodes a three-bit address to one of eight active-low outputs. This device features three chip select inputs, two active-low and one active-high, facilitating demultiplexing, cascading, and chip-selecting functions.

 

With an operating voltage range of 4.5V to 5.5V, the MC74HCT138AD offers TTL/NMOS compatible input levels and outputs that directly interface to CMOS, NMOS, and TTL logic. Its output drive capability is rated at 10 LSTTL loads, and it exhibits low input current of 1.0 µA.

 

The device is available in a 16-SOIC package, suitable for surface mount applications. It operates across a wide temperature range of -55°C to 125°C, making it suitable for various environmental conditions. The MC74HCT138AD is compliant with JEDEC Standard No. 7A requirements and is available in Pb-free packages.
