Nexperia USA Inc. 74AHCT86PW-Q100J

Overview

74AHCT86PW-Q100 from Nexperia is an automotive-qualified quad 2-input XOR gate in TSSOP14 package, operating from -40 °C to +125 °C with TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max), 4.5–5.5 V supply range, and propagation delay ≤9.0 ns (CL = 50 pF) - used for signal-level logic arbitration and parity generation in automotive body control modules.

For engineers reviewing the 74AHCT86PW-Q100 datasheet, 74AHCT86PW-Q100 pinout, 74AHCT86PW-Q100 application, or 74AHCT86PW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, overvoltage-tolerant inputs up to 5.5 V, Schmitt-trigger input action, balanced tPLH/tPHL timing, and compatibility with mixed-voltage system interfacing.

Technical Context

This device implements four independent CMOS-based XOR gates with TTL-level input thresholds, enabling direct interface with legacy 5 V TTL logic while powered from a 5 V rail. Each gate exhibits symmetrical propagation delays (tpd = tPLH = tPHL) and supports rail-to-rail output swing (VOH ≥ 3.70 V, VOL ≤ 0.55 V at IO = ±8 mA).

Inputs feature Schmitt-trigger action for noise immunity and overvoltage tolerance up to 5.5 V regardless of VCC, allowing safe operation in mixed-supply environments. The logic function follows standard XOR truth table (L/L→L, L/H→H, H/L→H, H/H→L) with no internal feedback or latching behavior.

FAQ

What is the maximum input voltage the 74AHCT86PW-Q100 can tolerate?

The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level, as confirmed in Section 7 (Limiting Values) and Section 2 (Features). This allows safe interfacing with 5 V signals even when VCC is lower, such as during brown-out conditions or mixed-supply domain crossings.

Does the 74AHCT86PW-Q100 support 3.3 V logic inputs?

No - the 74AHCT86PW-Q100 has TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and is specified only for 4.5–5.5 V supply. For 3.3 V systems, the 74AHC86PW-Q100 variant (CMOS input thresholds) is required, as detailed in Table 5 of the datasheet.

How does the Schmitt-trigger input improve noise immunity?

Each input incorporates hysteresis (typical ΔV = 0.3–0.5 V), meaning the rising and falling threshold voltages differ. This prevents multiple output transitions on slow or noisy input edges, as verified in Section 2 and functional description - critical for reliable operation near motors or solenoids in automotive settings.

Is the exposed pad on the TSSOP14 package electrically connected?

No - the TSSOP14 (SOT402-1) package used for 74AHCT86PW-Q100 has no exposed thermal pad. Unlike the DHVQFN variant (SOT762-1), this package relies on lead-frame conduction; thermal data in Section 7 confirms Ptot derating starts at 81 °C with 7.3 mW/K slope, consistent with standard TSSOP construction.
