STMicroelectronics 74ACT86 Quad 2-Input Exclusive OR Gate

The 74ACT86 from STMicroelectronics is a high-speed CMOS device that features four independent 2-input exclusive OR gates. This integrated circuit is designed to operate with an extended supply voltage range of 4.5V to 5.5V, making it suitable for interfacing with both TTL and CMOS logic levels. Its fast switching characteristics and low power consumption make it a preferred choice for a wide range of digital applications.

The device provides the essential exclusive OR function, which is a fundamental building block in digital logic circuits and systems. Each gate performs the Boolean function Y = A ⊕ B, where A and B are the inputs and Y is the output. This operation is crucial in applications such as parity generation and checking, binary addition, and digital signal processing.

The 74ACT86 features high noise immunity and the ability to drive up to 10 LSTTL loads. With a typical propagation delay of only 8ns at 5V, it ensures high-speed performance in critical applications. Additionally, the outputs are capable of sinking 24mA and sourcing up to 24mA, providing sufficient current for most peripheral devices.

This device is offered in several package options, including the DIP, SOIC, and TSSOP, which provides flexibility for various PCB layouts and space constraints. The input and output interface levels are compatible with TTL output levels, ensuring easy integration into existing designs without the need for level shifting.

In summary, the STMicroelectronics 74ACT86 is a reliable and efficient solution for implementing exclusive OR operations in digital systems. Its fast performance, compatibility with multiple logic levels, and versatility in applications make it an excellent choice for designers looking to optimize their digital circuits.
