SN74HC86DRE4 is a device belonging to the logic family of gates and inverters. It is a quad 2-input EXCLUSIVE-OR gate. The device has two separated inputs A and B and their sum output Q and inverted output Q, which provides a freedom to manipulate the schemes as per the desired needs. The device provides high speed operation at low power and low noise immunity with high noise margin across temperature and voltage level changes.The application field of SN74HC86DRE4 is varied and it is a versatile tool for a variety of applications including digital logic, analog circuitries, and timing applications. It is widely used in digital logic circuits like address decoding, priority encoders, and digital filter designs. Analog applications such as comparators, pulse width modulation and data mixers also commonly uses it.The working principle of SN74HC86DRE4 can be easily explained by a truth table. The truth table shows the output depending upon the combination of the two inputs denoted by A and B. The output will be high when A and B are different, and low when A and B are same.The truth table for the device is given belowA | B | Q | Q-- | -- | -- | --0 | 0 | 0 | 10 | 1 | 1 | 01 | 0 | 1 | 01 | 1 | 0 | 1From the truth table we can conclude that, when both input A and B logic level is low, the output Q is low and its compliment Q is high. Similarly if either of the A and B is high,the output Q is high and Q is lowBesides this, the SN74HC86DRE4 provides features like low power consumption, high noise immunity and small pin count. The device uses a technology called CMOS (Complementary Metal Oxide Semiconductor), which works on distributing power in both positive and negative directions, thus reducing the overall power consumption overall. The device is highly immune to noise due to its logic level threshold and is also operational over a wide temperature range making it an ideal choice for use in various environments.In terms of its safety features, the device contains an internal diode which clamps any overvoltage to the supply rails in case if one of the input is accidentally shorted to a voltage higher than the VCC supply. This feature prevents the burning of the circuit due to short.The output characteristics of the device were also designed to handle low capacitive load, making it suitable for driving wide range of loads. The logic family is designed to work with higher speed levels with the help of TTL buffers and voltage converters. In conclusion, SN74HC86DRE4 is an ideal device for applications which require reliable performance, low power consumption and wide temperature ranges. Its low power operation, wide noise immunity and safety features make it suitable for use in various operation environments. Its wide application field and easy to use EXCLUSIVE-OR logic gives a huge scope of creativity. It increases the flexibility of working in various digital, analog and time-based applications.
