The SN74AUC2G86DCUR is a dual 2-input positive-OR gate with a Schmitt-trigger input. It is an integrated circuit manufactured using the CMOS process and designed for use in digital circuits dependent on low power consumption and high restoration characteristics. This device is especially useful in applications requiring hysteresis, noise immunity, and power-on reset, such as noise-immune control of mechanical devices, controllers, digital displays, and so on.

Application Field

The SN74AUC2G86DCUR is particularly useful in applications where noise-sensitivity is a concern, and where the environment requires enhanced immunity to electrical noise in order to ensure consistent operation. Specifically, this device serves as an extremely low-power, noise-immune interface between two different circuits in a system, most often with automated systems which require precise timing and electrical signal control (e.g., motor drivers and control systems).

For instance, the SN74AUC2G86DCUR can be used in devices such as air compressors, diesel fuel pumps, industrial and HVAC controllers, gas valves, and so on, in order to condition signals for reliable operation and for reducing the chances of data errors caused by signal noise.

Working Principle

The SN74AUC2G86DCUR is an integrated circuit including two CMOS inverter stages and two OR gate stages. These devices can be used to condition CV signals for precise timing and actuation in a precise order and in a reliable manner.

Each 2-input positive-OR gate consists of two CMOS inverters connected in series with the gate output connected between them. The inputs of both inverters are connected to the gate inputs. When logic "1" is presented at either gate inputs, a logic "1" is established or maintained at the gate output, otherwise the output is logic "0".

In addition, the device includes a Schmitt-trigger input stage, which adds immunity to noise and allows the restoration of a true logic level after transients. Furthermore, the device prevents unwanted oscillations, ensuring consistent operation.

Lastly, the SN74AUC2G86DCUR offers extremely low power consumption, drawing at minimal 4.5 μA from the power-supply pins. This allows for extended battery life and improved reliability of the device.
