CD74ACT86M

The CD74ACT86M is a quadruple 2-input exclusive-OR gate IC manufactured by Harris Semiconductor. This device performs the Boolean function Y = A ⊕ B or Y = A\B + AB\ in positive logic. It is commonly used as a true/complement element, where if one input is low, the other input is reproduced in true form at the output, and if one input is high, the signal on the other input is reproduced inverted.

Key electrical characteristics include a 4.5V to 5.5V operating voltage range and an output drive current of ±24mA. The propagation delay is rated at 14.6ns at 5V and 50pF. The inputs are TTL-voltage compatible, offering speeds comparable to bipolar F, AS, and S families with significantly reduced power consumption.

This component is housed in a 14-SOIC surface mount package. The operating temperature range is -55°C to 125°C. The CD74ACT86M is noted as obsolete and not recommended for new designs, suggesting that alternative or replacement parts should be considered for new projects.

Applications for this XOR gate include arithmetic circuits, data handling, and signal manipulation where exclusive-OR logic is required. Its robust design includes SCR-latchup-resistant CMOS process and circuit design, exceeding 2-kV ESD protection per MIL-STD-883, Method 3015.
