Nexperia USA Inc. 74AHC1G86GW-Q100,1

Overview

74AHC1G86GW-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 2.0–5.5 V, overvoltage-tolerant inputs up to 5.5 V, and propagation delay as low as 3.4 ns (VCC = 5.0 V, CL = 15 pF). It serves as a level-translating logic gate in automotive body control modules requiring robust noise immunity and mixed-voltage signal interfacing.

For engineers reviewing the 74AHC1G86GW-Q100 datasheet, 74AHC1G86GW-Q100 pinout, 74AHC1G86GW-Q100 application, or 74AHC1G86GW-Q100 equivalent, key selection criteria include its AEC-Q100 qualification, input-level compatibility (CMOS), TSSOP5 package footprint, and verified performance under extended temperature and dynamic load conditions.

Technical Context

This device implements a single 2-input XOR function with symmetrical output impedance and balanced propagation delays between A→Y and B→Y paths. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V peripherals without external level shifters.

The 74AHC1G86GW-Q100 uses standard CMOS input thresholds (VIH ≥ 3.85 V at VCC = 5.5 V; VIL ≤ 1.65 V), delivers VOH ≥ 3.94 V (IO = −8 mA, VCC = 4.5 V), and maintains VOL ≤ 0.36 V (IO = 8 mA), ensuring reliable rail-to-rail switching across its full operating range.

FAQ

Is the 74AHC1G86GW-Q100 pin-compatible with the 74AHCT1G86GW-Q100?

Yes - both share identical TSSOP5 (SOT353-1) pinout, thermal profile, and mechanical footprint. The only functional difference is input threshold compatibility: 74AHC1G86GW-Q100 requires CMOS-level inputs (VIH ≥ 3.85 V at 5.5 V), while 74AHCT1G86GW-Q100 accepts TTL-level inputs (VIH ≥ 2.0 V). No PCB change is needed for substitution.

What is the maximum capacitive load this device can drive reliably?

The 74AHC1G86GW-Q100 is characterized up to 50 pF load capacitance, with guaranteed propagation delay (tpd ≤ 8.5 ns) and output voltage swing (VOH ≥ 3.70 V, VOL ≤ 0.55 V) across −40 °C to +125 °C. Driving >50 pF may increase delay unpredictably and degrade noise margins; external buffering is recommended beyond this limit.

Does this device require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be tied directly to VCC or GND. Floating inputs cause increased ICC, unpredictable output states, and potential oscillation due to internal input stage metastability. The datasheet explicitly prohibits resistor-based termination, as it degrades noise immunity and violates AEC-Q100 reliability test conditions.

Can the 74AHC1G86GW-Q100 operate at 2.0 V supply while maintaining full speed performance?

No - at VCC = 2.0 V, propagation delay increases to 14.0 ns (max, CL = 15 pF) and output drive weakens (VOH ≥ 1.5 V, VOL ≤ 0.5 V). For 2.0 V systems, verify timing closure with worst-case delay and confirm that downstream logic interprets the reduced voltage swing as valid HIGH/LOW. Performance is optimized at VCC ≥ 3.0 V.
