The 74LV139N,112 is a member of the family of high–speed low– power CMOS logic level–converter which is suitable for a wide range of applications. This device provides low power consumption and clamping diodes for board-level ESD protection. It is used in switching, multiplexing, and decoding in logic applications.

The 74LV139N,112 consists of two 2-to-4 line decoders/demultiplexers with complementary outputs. The device features a selectably–enabled output and selection of active–low or active–high output enable. The functions of the two decoders are controlled by a pair of inputs (G1, G2) and by the output enable pin (G3). The G1 and G2 inputs are used to select one of four paths from the A0 and A1 input pins to the Y0, Y1, Y2, and Y3 output pins. The output enable pin functions as an enable/disable control for all of the outputs. With the output enable pin high, all outputs will be at the logic level determined by the selection of the inputs. If the output enable pin is low, all outputs will be at logic “0” regardless of the selection of the inputs.

In addition, this device has a low power consumption, making it ideal for portable or other low power applications. It is also designed to provide a high level of immunity to switching noise, making it suitable for communications and control applications. It features a wide operating voltage range of 2.0 V to 6.0 V.

The 74LV139N,112 can be used in a wide variety of applications, including digital network communications, video signal switching, signal routing, and signal conditioning. It can also be used in other logic applications such as signal processing, data multiplexing, memory decoding, and address decoding.

In operation, the 74LV139N,112 multiplexes the two input lines A0 and A1 to four output lines Y0, Y1, Y2, and Y3. The select lines G1 and G2 are used to choose which of the four output lines is active. The output enable pin (G3) is used to activate or deactivate the device. When the output enable pin is low, all of the outputs will be at logic “0” regardless of the selection of the inputs. When the output enable pin is high, the selection of input lines A0 and A1 determines which output line Y0, Y1, Y2, or Y3 is active.

The high speed of this device makes it suitable for high speed applications such as digital signal processing and communications. The low power consumption makes it ideal for low power applications such as portable devices. The wide operating voltage range makes it suitable for low voltage applications and the high level of noise immunity makes it suitable for communications and control applications. In addition, the device has “Clamp Diode ESD and Polarity Protection,� making it ideal for board-level ESD protection.

The 74LV139N,112 can thus be used to switch, multiplex, or decode signals in a variety of applications. It is based on high-speed CMOS logic and has a wide operating voltage range, low power consumption, high noise immunity, and board-level ESD protection to make it suitable for a wide range of uses.
