Logic Gates and Inverters, like the SN74LVC1G11DBVR, are fundamental building blocks of digital circuits. They are used to perform elementary logic operations such as Boolean AND, OR, and NOT operations. An SN74LVC1G11DBVR is a single gate device, meaning it can perform a single logic operation at a time. It is a dual-input non-inverting Schmitt trigger of the CMOS logic family. This application note will discuss the various application fields and working principles of the SN74LVC1G11DBVR.

Application Field

The SN74LVC1G11DBVR is designed for applications that require both low supply voltage and low input current, such as battery-powered devices and automotive systems. The device is generally used for noise filtering and signal conditioning. It can be used to reduce and/or debounce contact noise generated by switches and is particularly useful in noisy environments. Other applications that utilize the SN74LVC1G11DBVR are communication interface circuits, power supply sequencing devices, and logic circuits.

Working Principle

The SN74LVC1G11DBVR is a positive-logic gate. Its logic diagram is within scope of a standard XOR gate, along with some additional packages for the dual-input non-inverting schmitt trigger. The device incorporates several input and output conditioning circuits to improve its noise immunity, making it ideal for noisy applications. The device contains two independent 1-input Schmitt triggers with a common output. The two inputs, A and B, each have a Schmitt trigger with an active-high and active-low level threshold. The device\'s output is logic high when either or both the inputs are logic high, and logic low when both inputs are logic low.

The SN74LVC1G11DBVR has two input levels and two output levels. The input levels are defined by the threshold voltage, Vth. An input voltage below the lower threshold (Vtl) will be interpreted as logic low while any voltage above the higher threshold (Vth) will be interpreted as logic high. Any input voltage between the two thresholds (Vthl) will generate an indeterminate result. The output levels are defined by the High Level Output Voltage (Voh) and Low Level Output Voltage (Vol). The Voh will be higher than the supply voltage (Vcc) for logic high output and the Vol will be lower than the ground potential for logic low output.

Conclusion

The SN74LVC1G11DBVR is a dual-input non-inverting Schmitt trigger of the CMOS logic family. Its low supply voltage and low input current requirements make it suitable for a wide range of demanding applications, including battery-powered devices, sensor interfaces, communication interfaces, power supply sequencing and logic circuits. Its two independent Schmitt triggers enable it to accurately sense noise voltages, improving noise immunity in noisy environments. The device’s two interdependent input and output levels, define its logic operation of comparing the input voltage with two references, low threshold and high threshold, and outputting logic high in a true input and logic low in a false input.
