The CD74HCT238EG4 is a 3-to-8 bit demultiplexer with three active-low outputs and an active-low enable input. It is designed to select one-of-eight data sources and can be used as a general purpose multiplexer or demultiplexer. The device can also be used as a 1-of-4 decoder/demultiplexer with active-low outputs.

The device is constructed with a number of standard CMOS inverters, gates and multiplexers. It consists of three data sources whose addresses are derived from three address inputs. The inputs are labeled A, B and C, and the outputs are labeled Y0 - Y7. A logic-low enable input (invEN) disables all outputs when tied to GND.

The most common application for this device is to act as a multiplexer or demultiplexer. This can be done by connecting the three address inputs to a decoder, such as a CD74HCT154M96, or in the case of a demultiplexer, to the outputs of a latch. This has the effect of multiplexing or demultiplexing the seven data sources connected to the Y0 - Y7 outputs. Enable logic can then be used to control the output enable (OE) pin, which disables all outputs when active low.

Another application for the CD74HCT238EG4 is as a 1-of-4 decoder/demultiplexer. By connecting all three address inputs to the same logic signal, the device can be used to select one output and disable the others. This can be used, for example, in interactive devices that need to select one output at any given time. A logic-high enable (OE) will enable the selected output, while a logic-low enable (OE) will disable all outputs.

The CD74HCT238EG4 is also often used as a bus switch, or as a memory or program selection device. The device features low power dissipation, low-voltage operation, and is suitable for single-supply applications. It is CMOS-based and features minimum power consumption and low internal noise.

The CD74HCT238EG4 is a versatile device with a wide range of applications. Its methods of operation make it suitable for a variety of applications, from multiplexing and demultiplexing to memory selection and bus switching. It is a reliable, low-cost solution and is available in many packages. Such an integrated circuit is an efficient way of designing cost-effective systems.
