The 74HC238ADR2G is a 3 to 8 line decoder/demultiplexer logic device. It is designed to be used in high-performance low-power CMOS applications. The 74HC238ADR2G performs the conversion of information from a 3-line binary coded input to an 8-line active-high output. It is an ideal solution for address decoding and line selection in data communications systems and also for memory decoding and memory selection in microcomputers.

The 74HC238ADR2G features an active-low enable input (E1) and an active-high enable (E2) input. When the enable input is low, the outputs are disabled. When the enable input is high, the outputs take their normal logic state. The device also features a select input for selecting between the active-high and active-low output states.

The 74HC238ADR2G has a wide power supply range, making it suitable for both digital and analog applications. It allows for a maximum current output of 25mA, making it suitable for driving high current devices. The device operates on a single 5V supply and has a typical propagation delay of 3.2ns.

The 74HC238ADR2G is particularly useful in address decoding and data multiplexing applications in which a 3-bit code is applied to the inputs and the outputs enable lines allow the output enable lines to select the appropriate output depending on the input code. The 74HC238ADR2G also has an output enable line for decoder applications, and other modes of operation such as data multiplexers, shift registers and programmable array logic (PAL) devices.

The 74HC238ADR2G has a wide operating temperature range of -40°C to +85°C. This device is also available in various package options for use in different applications. For example, the device is available in both a small outline (SO) and an ultra-small outline (US) package for use in low-power, high-performance applications.

In summary, the 74HC238ADR2G is a 3 to 8 line decoder/demultiplexer logic device. It is designed to be used in high-performance low-power CMOS applications and has a wide power supply range and low propagation delay. It allows for a maximum current output of 25mA, making it suitable for driving high current devices. It is ideal for address decoding and line selection in data communications systems, memory decoding and memory selection in microcomputers, data multiplexers, shift registers, and programmable array logic (PAL) devices. The device is available in various package options for use in different applications.
