4LS138 1-To-8 Decoder/Demultiplexer IC
The 74LS138 decodes one of eight lines dependent on the conditions at the three binary select inputs and the three enable inputs. It is intended to function in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS138 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.
