Product details

Single XOR gate with Schmitt-trigger inputs — what that buys you

The TI SN74AHC1G86DCKT is a single 2-input XOR gate from the 74AHC family, with Schmitt-trigger inputs on both pins. The Schmitt trigger means the input thresholds are 0.5 V to 1.65 V (low) and 1.5 V to 3.85 V (high) across the supply range — so a slow-rising or noisy signal from a sensor or a long PCB trace won't cause the output to chatter or oscillate. It's a glue-logic part for industrial control boards, telecom line cards, or any mixed-voltage design where you need to XOR two digital signals and can't afford false edges.

2 V to 5.5 V supply — one part for 3.3 V and 5 V rails

The supply range covers 2 V to 5.5 V. At 5 V the max propagation delay is 8.8 ns into a 50 pF load. Quiescent current is 1 µA max. The 8 mA output drive at both high and low is typical for this family.

Active lifecycle — no LTB risk for new designs

TI lists this part as Active with ROHS3 compliance. No end-of-life notices are on record. For a BOM freeze, this is a safe choice — no PCN watch needed for the foreseeable future. The 74AHC series is a mature logic family with broad distribution support, so lead times are typically standard through the channel.

Frequently asked questions

Is SN74AHC1G86DCKT a Schmitt trigger XOR gate?

Yes. Both inputs have Schmitt-trigger hysteresis, which cleans up noisy or slow edges. The low-level threshold is 0.5 V to 1.65 V and the high-level threshold is 1.5 V to 3.85 V, depending on supply voltage.

Does SN74AHC1G86DCKT have an equivalent or replacement?

The closest functional equivalent is the SN74AHC1G32DCKT, which is an OR gate in the same package and supply range. For a direct XOR replacement, the SN74AHC1G86 in other package options (like SOT-23) is pin-compatible but check the footprint. No exact second-source from another manufacturer is listed in TI's cross-reference.
