Texas Instruments Signal Switches, Multiplexers, Decoders SN74HC138D

The SN74HC138D 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 and data reception, and it features active low outputs, where the selected output is low. The SN74HC138D is available in a 16-pin SOIC package, with a body size of 9.90 mm x 3.90 mm. It is applicable in various fields, including LED displays, servers, building automation, and factory automation.
