MC74AC138MG is a 3-to-8 line decoder/demultiplexer. It is a member of the 74AC Series digital logic family with low power Schottky TTL (LSTTL) technology and is the most popular types of Decoders, Multiplexers, and Signal Switches. Manufactured by ON Semiconductor, the MC74AC138MG is a high-speed device capable of operating at frequencies up to 50 MHz. This device is available in a 25-lead PDIP package.This device receives three binary address inputs (A0, A1, A2) and decodes them to one of eight active low outputs (Y0-Y7). This device provided greater flexibility and a much larger number of optional output lines as compared to simpler 3-to-8 decoders like the MC74AC138G. When the input binary codes are low (0) at A0, A1, and A2, at the same time, all of the outputs Y0 - Y7 will be high (1). The MC74AC138MG is suitable for interfacing to many types of bus systems including address/data buses with chip-select signals. It can be used for implementing addressable memory, arbitrary logic functions, priority encoders and interrupt controllers. This device is also used in peripheral devices such as serial and parallel ports, memory mapping, and timing functions. The MC74AC138MG consists of an array of gates each with three inputs – A0, A1 and A2. The gates switch the associated output to a high level whenever the three inputs correspond to the binary number that is encoded on the gate. The outputs are ORed together to form the Y output.The internal logic of the MC74AC138MG is composed of three 2-input NAND gates per output. The gates are controlled by the three binary address inputs. When the address input is all low, the outputs are activated and all high. When the address is decoded, the output corresponding to that address will be the only one active and low. All other outputs will be high. The MC74AC138MG is designed to work with low power Schottky TTL (LSTTL) devices and can operate at frequencies up to 50MHz. This device is designed to work with 3.3V and 5V power supplies, offering flexibility in design. It also provides very low power consumption, and enables operation with power supply currents as low as 1mA.The MC74AC138MG offers a variety of features which make it ideal for many different applications. It is very reliable, with a MTBF of 51.2 million hours. This device is also RoHS compliant, making it suitable for use in environments where restricted materials or hazardous substances are prohibited. In conclusion, the MC74AC138MG is a 3-to-8 line decoder/demultiplexer, a member of the 74AC Series digital logic family with low power Schottky TTL (LSTTL) technology and is one of the most popular types of Logic - Signal Switches, Multiplexers and Decoders available. It is suitable for many different applications due to its low power consumption, high speed operation, and flexible power supply options. This device is very reliable and RoHS compliant, making it a perfect choice for designers when flexibility and a low-power solution are required.
