Introduction to NLV74AC157DR2G

The NLV74AC157DR2G is an integrated circuit (IC) developed by ON Semiconductors, a semiconductor company based in Phoenix, Arizona, USA. The NLV74AC157DR2G is a monolithic CMOS logic “signal switch” and is part of ON Semiconductor’s AC Logic family. The NLV74AC157DR2G is a “four-to-one line multiplexer” which is used to isolate input signals and send them to their respective output to be used as part of a logic circuit.

Application Fields of NLV74AC157DR2G

The NLV74AC157DR2G is essential for applications that require isolating one signal from a group of inputs, such as when sending one signal from multiple sources (multiplying) or combining multiple signals from various sources (adding). The NLV74AC157 DR2G is typically found in computers, microcontrollers, and other digital logic circuits where isolating and combining signals is essential.

Working Principle of NLV74AC157DR2G

The NLV74AC157 DR2G contains four input control pins (A0,A1,B0, and B1) and four output control pins (C0,C1,D0, and D1). When the input control pins are “on” or “high,” then the corresponding output control pin is also “on” or “high.” When the input control pins are “off” or “low,” then the corresponding output control pin is also “off” or “low.” This allows the user to isolate a signal from a group of inputs and send it to its desired output.The NLV74AC157DR2G has a maximum switching speed of 1 µs (microsecond) and a maximum power consumption of 125 mW (milliwatts). The NLV74AC157DR2G also has up to 25 mA of “sinking” current (the ability to draw current), allowing it to control more than one output pin simultaneously. Finally, the NLV74AC157DR2G is rated to operate at temperatures as low as -55 ºC and as high as +125 ºC. Its small size (eight-pin SO package) also makes it an excellent choice for tight logic circuits.

Conclusion

The NLV74AC157DR2G is a monolithic CMOS logic signal switch, which is part of ON Semiconductor’s AC Logic family. It is used to isolate one signal from a group of inputs and send it to its output. This is essential for applications where signals from multiple sources need to be combined or multiplied. The NLV74AC157DR2G has up to 1 µs of switching speed and up to 25 mA of sinking current. It is rated to operate at temperatures ranging from -55 ºC to +125 ºC and comes in an eight-pin SO package, making it a great choice for tight logic circuits.
