Quad 2-input XOR gate for automotive and industrial logic
The Texas Instruments SN74HC86QPWRQ1 is a quad 2-input XOR (exclusive OR) gate from the 74HC family, qualified to AEC-Q100 for automotive applications. It operates over a 2 V to 6 V supply range and the full -40°C to 125°C temperature span, making it a direct fit for under-hood ECUs, body controllers, and industrial control boards that need a reliable XOR function across voltage domains. Four independent gates in a single 14-TSSOP package save board space compared to discrete logic.
25 ns propagation delay — timing margin in the bus
The 25 ns max propagation delay at 6 V with a 50 pF load sets the timing budget for XOR operations in clock distribution, parity generation, or data-path comparison.
Active lifecycle — no LTB risk for production BOMs
The SN74HC86QPWRQ1 carries an active lifecycle status and is ROHS3 compliant. There is no last-time-buy or end-of-life notice on this part, so it can be specified into new automotive or industrial designs without near-term obsolescence risk.
14-TSSOP footprint — fits existing 4.4 mm wide layouts
The 14-TSSOP package (4.40 mm body width) is a common logic footprint shared with many 74HC and 74LVC devices. It mounts directly to standard surface-mount pads and is compatible with reflow profiles used for automotive-grade assemblies.
Sourcing and availability
This part is sourced through independent distribution and quoted to order against an RFQ. For dual-sourcing or a faster logic family, the SN74LVC86APWR is a pin-compatible 74LVC XOR gate with 4.4 ns propagation delay, but it is not AEC-Q100 qualified — verify the temperature grade matches your application.
