The MC74ACT139MEL is a dual 1-of-4 decoder/demultiplexer family logic device. It is designed to provide 1-of-4 address decoding or data demultiplexing with active LOW (GTL / GTL2 / HSTL / PVT) outputs. The relatively low power consumption combined with very high noise immunity makes the device ideal for use in a range of different applications, from industrial through to consumer electronics.

The MC74ACT139MEL is a 3-state device, which means it can be used as both a decoder as well as a multiplexer. The device is made up of four independent AND gates, each with two inputs and one output. The device is built using CMOS logic, and therefore the inputs can be both TTL and CMOS compatible. The outputs of the device are in the GTL / GTL2 / HSTL or PVT format and are active LOW, meaning they are activated with a logical LOW signal at the inputs. The MC74ACT139MEL can be powered down by reversing the polarity of the VDD and VSS pins.

The MC74ACT139MEL is a versatile device, which can be used in a variety of different applications. The logic device can be used in systems as an address decoder, or as a data demultiplexer, meaning it can be used to select one out of four possible inputs. The device can also be used in the conversion of parallel data to serial and vice versa. The device is also ideal for use in very low-power applications such as automated meter reading, medical equipment and environmental sensing.

The MC74ACT139MEL also has a range of features which make it a great choice for many different systems and applications. The device is capable of operating at clock rates up to 30Mhz which makes it suitable for use in a range of different high-speed applications. The device also features high-immunity against noise interference and can withstand up to 10V of electrostatic discharge, making it a great choice for applications in harsh environments. The MC74ACT139MEL also offers latch-up free operation, which helps to reduce the chances of unwanted outputs.

Overall, the MC74ACT139MEL is an ideal logic device for a range of different applications. The decoder/demultiplexer family logic device is designed to provide low-power and high noise immunity, making it a great choice for a wide range of different systems and applications. The device’s ability to operate at clock rates up to 30Mhz and its feature of latch-up free operation make it a great choice for a range of industrial through to consumer electronics applications.
