ON Semiconductor NLV74HC138ADR2G Decoder/Demultiplexer

The NLV74HC138ADR2G from ON Semiconductor is a high-performance, 3-to-8 line decoder/demultiplexer integrated circuit designed for use in a wide range of digital applications. This IC is a member of the high-speed CMOS family, offering low power consumption and robust noise immunity characteristics inherent to CMOS technology.

This versatile component is capable of decoding information from a 3-bit binary input to one of eight mutually exclusive outputs. The device features three binary select inputs (A, B, and C), an enable input (G2A), and two active-low enable inputs (G1 and G2B), which must be satisfied to enable the device. When enabled, the corresponding output will go low, indicating the selection of that particular output line.

The NLV74HC138ADR2G is designed with a balanced propagation delay and transition times, providing reliable and fast performance suitable for high-speed operation in digital systems. Its multiple enable inputs make it an ideal choice for implementing multiple demultiplexers with a common address input connection.
