Nexperia USA Inc. 74HC1G86GV-Q100H

Overview

74HC1G86GV-Q100 from Nexperia is a single 2-input CMOS-exclusive-OR gate qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V. It delivers symmetrical output impedance, balanced propagation delays (9–22 ns at VCC = 4.5–6.0 V, CL = 50 pF), and integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC - used in automotive body control modules for signal-level logic arbitration.

For engineers reviewing the 74HC1G86GV-Q100 datasheet, 74HC1G86GV-Q100 pinout, 74HC1G86GV-Q100 application, or 74HC1G86GV-Q100 equivalent, key selection criteria include its automotive-grade temperature range, CMOS input compatibility, 5-pin SC-74A (SOT753) package footprint, and verified EXOR truth table compliance per IEC 60617-12.

Technical Context

This device implements a single 2-input XOR logic function with fully buffered inputs and outputs, supporting both combinatorial and synchronous logic paths in safety-critical automotive subsystems. Its input clamp diodes allow direct connection to external signals up to VCC + 0.5 V when current-limited, eliminating need for external protection in LIN bus interface conditioning or door module status encoding.

The 74HC1G86GV-Q100 uses standard HC-series CMOS logic thresholds (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), ensuring noise immunity >1.35 V under worst-case conditions, and exhibits matched tPLH/tPHL propagation delays within ±1 ns across temperature - critical for deterministic timing in seatbelt pretensioner enable logic.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks parametric degradation and violates AEC-Q100 stress limits, even if clamping diodes protect inputs - sustained 7.0 V operation is prohibited per Table 5 limiting values.

Can this device interface directly with 12 V automotive signals?

Yes - input clamp diodes allow safe connection to signals up to VCC + 0.5 V when series current-limiting resistors are used. For 12 V signals, a minimum 1 kΩ resistor limits input current to <12 mA, staying within the ±20 mA clamp rating specified in Table 5, enabling direct interface without external protection diodes.

Is the 74HC1G86GV-Q100 pin-compatible with the 74HCT1G86GV-Q100?

Yes - both share identical SC-74A (SOT753) 5-pin pinout, marking location, and mechanical footprint. The only functional difference is input threshold levels: HC version requires CMOS-compatible inputs (VIH ≥ 3.15 V at 4.5 V), while HCT version accepts TTL-level inputs (VIH ≥ 2.0 V), allowing drop-in replacement where input drive matches.

Does this device support hot-swap or live-insertion in powered systems?

No - the 74HC1G86GV-Q100 lacks Ioff (power-off protection) or IOZ (three-state with power-down) features. Applying VCC after inputs are driven may cause excessive current through internal clamps. Power sequencing must ensure VCC is stable before applying input signals, per Section 8 limiting values and JEDEC JESD78 latch-up guidelines.
