Texas Instruments SN74ACT86/SN74ACT86-Q1 2-Input Exclusive-OR Gates
Texas Instruments SN74ACT86/SN74ACT86-Q1 Quad 2-Input Exclusive-OR Gates are quadruple 2-input exclusive-OR gates. In positive logic, the devices perform the Boolean function Y = A ⊕ B or Y = AB + AB. A typical application is as a complement/true element. If one of the inputs is low, the other input is reproduced in a true form at the output. If one of the inputs is high, the signal on the other input is reproduced as inverted at the output. The Texas Instruments SN74ACT86-Q1 devices are AEC-Q100 qualified for automotive applications.
