Additional Details

The TC74HC86AF operates from a supply voltage range of 2V to 6V, making it versatile for a variety of applications. It is available in a small outline integrated circuit (SOIC) package suitable for surface mount technology. The inputs are equipped with protection circuits against static discharge. The exclusive-OR gate outputs a high signal only when one, but not both, of its inputs are high. When both inputs are the same (both high or both low), the output is low. This function is vital in parity generation and checking, code conversion, and arithmetic operations.

The operating temperature range of the TC74HC86AF is typically between -40°C to +85°C. The device meets or exceeds industry standards for CMOS integrated circuits. The symmetrical output impedance allows for balanced signal propagation, minimizing signal distortion and improving overall system performance. Its high noise immunity ensures reliable operation even in electrically noisy environments, making it suitable for industrial control systems and automotive applications.
