Product details

Quad 2-input XOR in the 74HC family

The SN74HC86DT is a quad 2-input XOR (Exclusive OR) gate from Texas Instruments' 74HC series, packaged in a 14-SOIC (0.154", 3.90mm width) for surface-mount assembly. It operates across a 2V to 6V supply range and draws a maximum quiescent current of 2 µA, making it suitable for battery-powered or low-power logic stages.

Propagation delay and output drive

Maximum propagation delay is 17 ns at 6V with a 50 pF load — the 74HC family's CMOS output stage delivers 5.2 mA source and sink at the rated voltage, enough to drive one or two standard CMOS inputs without a buffer. The 2 µA quiescent current floor means the gate adds negligible static load to the supply rail. Input logic levels are specified as 0.5V to 1.8V for low and 1.5V to 4.2V for high across the 2V-6V supply range, ensuring TTL-compatible thresholds at 5V operation.

Frequently asked questions

What is the SN74HC86DT used for?

It is a quad 2-input XOR gate used for binary addition, parity checking, and data comparison in digital logic circuits operating from 2V to 6V.

Is the SN74HC86DT a direct replacement for the SN74HC27APWR?

No. The SN74HC27APWR is a triple 3-input NOR gate in a different package (TSSOP) and different logic function. They are not pin-compatible or functionally interchangeable.
