Rochester Electronics Logic - Signal Switches, Multiplexers, Decoders SN74HC138DG4

The SN74HC138DG4 is a high-speed 3-line to 8-line decoder/demultiplexer designed for applications requiring minimal propagation delay. It operates within a 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 a typical propagation delay of 15 ns, making it suitable for high-performance memory decoding and data routing. This decoder includes three enable inputs to facilitate cascading or data reception, and it has active low outputs, meaning the selected output is low while the others remain high. The SN74HC138DG4 is applicable in various fields, including LED displays, servers, building automation, and factory automation. Its compact 16-pin package options include SOIC, SSOP, PDIP, and TSSOP, allowing for versatile integration into different designs.
