Texas Instruments High-Performance Analog Logic - Logic - Signal Switches, Multiplexers, Decoders - SN74HC138DR SN74HC138DR

The SN74HC138DR is a high-speed 3-line to 8-line decoder/demultiplexer designed for applications requiring minimal propagation delay. It operates within a wide voltage range of 2 V to 6 V and features low power consumption with a maximum supply current of 80 ¬µA. The device can drive up to 10 LSTTL loads and provides active low outputs, meaning the selected output is low while others remain high. It incorporates three enable inputs, facilitating cascading or data reception, which is beneficial in complex circuit designs. This decoder is suitable for various applications, including LED displays, servers, and automation systems. The typical propagation delay is 15 ns, making it effective for high-performance memory systems where it can minimize system decoding delays. The SN74HC138DR is available in a 16-pin SOIC package and operates within a temperature range of -40¬8C to 85¬8C. It is a commonly used part with sufficient supply and demand status, making it a reliable choice for engineers in need of a robust decoding solution.
