SN74F138NSR TI Decoder/Demultiplexer | 16-SO | 3-to-8 Line, 4.5V-5.5V

Product Overview

The SN74F138NSR is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for memory decoding and data routing applications. Housed in a 16-pin SOIC package, it operates over a wide voltage range of 4.5V to 5.5V, making it suitable for 5V logic systems. The device features three enable inputs (two active low and one active high) for easy cascading and expansion. With typical propagation delays of 6.5ns and low power consumption, it is ideal for high-speed digital systems.
