It combines the familiar XOR function — output high when inputs differ — with built-in hysteresis that cleans up slow or noisy edges, making it a drop-in upgrade for systems that struggle with the standard 74HC86's input thresholds under noisy supply or long traces. Each of the four independent gates drives up to 7.8 mA at the output, and the device operates across a 2V to 6V supply range, covering 3.3V and 5V rails without a level translator. The 14-SOIC package is the same footprint as the classic 74HC86, so a board spin is not required to gain the noise margin. Temperature range spans -40°C to 125°C, suited for industrial motor drives, automotive body controllers, and outdoor telecom line cards that see thermal cycling. ## Schmitt-trigger hysteresis — what it buys you The Schmitt-trigger inputs define the 74HCS series versus the standard 74HC family. On a conventional HC gate, a slowly rising input — from a capacitor-coupled sensor, a long PCB trace, or a debounced switch — can sit in the linear region long enough to cause oscillation or double-clocking. The SN74HCS86DR's hysteresis (1V to 3V low-level threshold, 1.5V to 4.2V high-level threshold at 5V) provides a clean snap-action transition. In a 5V system, that means a rise time that would glitch an HC86 passes cleanly through the HCS gate. The propagation delay is 12ns at 6V with a 50pF load, comparable to the HC86, so speed is not sacrificed for the noise margin. ## Active lifecycle, no LTB risk There is no last-time-buy notice, and the part is not marked NRND. ROHS3 compliance is confirmed, and the standard ordering codes (Tape & Reel, Cut Tape) are available through normal distribution. For a BOM line that needs a quad XOR gate with improved noise immunity, this part is a current-production choice with no near-term end-of-life concern.","metaTitle":"SN74HCS86DR XOR Gate, Schmitt Trigger, 14-SOIC","metaDescription":"TI SN74HCS86DR quad 2-input XOR gate with Schmitt-trigger inputs. 2V to 6V supply, -40°C to 125°C, 12ns propagation delay.

The key difference is the Schmitt-trigger inputs on the HCS version, which provide hysteresis for cleaner switching on slow or noisy input signals. Propagation delay and output drive are similar, so in a board that already uses an HC86, swapping to the HCS86 gains noise margin without a layout change. Verify input thresholds against your system's signal levels, but for the vast majority of 3.3V or 5V logic applications, it is a drop-in upgrade."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HCS86DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HCS86DR when reusing this data.
