onsemi Signal Switches, Multiplexers, Decoders MC74HCT138ADG

The MC74HCT138ADG is a 1-of-8 decoder/demultiplexer designed for high-performance applications. It features LSTTL compatible inputs and can be used as a level converter for interfacing TTL or NMOS outputs to high-speed CMOS inputs. The device decodes a three-bit address to one of eight active-low outputs and includes three chip select inputs, facilitating demultiplexing and cascading functions. It operates within a voltage range of 2 to 6 V and has a low input current of 1.0 µA. The output drive capability supports up to 10 LSTTL loads, and the device is compliant with JEDEC Standard No. 7A. The MC74HCT138ADG is available in a Pb-free, halogen-free, and RoHS compliant package, making it suitable for environmentally conscious designs. Engineers may find this product beneficial for applications requiring reliable signal routing and level shifting in digital circuits.
