SN74HC138N Texas Instruments Components


The SN74HC138N is a 3-wire to 8-wire decoder/demultiplexer from Texas Instruments. This device is specifically designed for high performance memory decoding or data routing applications. XT-ShenZhen can provide an amazing experience for your procurement work.

Because the SN74HC138N device can provide an extremely short propagation delay time for the application. This makes the device ideal for high-performance memory decoding and data routing applications.
Decoders can help minimize the impact of decoding in high-performance storage systems. A high-speed memory using a fast enable circuit can be used with the decoder. At this time, the delay time of the decoder and the enable time of the memory are less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible.
