Nexperia USA Inc. 74HCT1G86GV-Q100H

Overview

74HCT1G86GV-Q100 from Nexperia is a single 2-input EXCLUSIVE-OR gate in SC-74A (SOT753) package, qualified to AEC-Q100 Grade 1 for automotive use. It operates from -40 °C to +125 °C with TTL-compatible input levels, 4.5–5.5 V supply range, and delivers balanced propagation delays (13 ns typ @ 4.5 V/50 pF). It serves as a logic-level combiner in vehicle body control modules for door lock status arbitration.

For engineers reviewing the 74HCT1G86GV-Q100 datasheet, 74HCT1G86GV-Q100 pinout, 74HCT1G86GV-Q100 application, or 74HCT1G86GV-Q100 equivalent, key selection criteria include automotive qualification grade, TTL input compatibility, SC-74A thermal derating profile (3.8 mW/K above 85 °C), and guaranteed 2.0 V to 5.5 V operation across temperature extremes.

Technical Context

This device implements a single 2-input XOR function with symmetrical output impedance and balanced tPLH/tPHL propagation delays. Its inputs feature integrated clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

The logic behavior follows standard Boolean XOR: Y = A ⊕ B, with truth table L/L→L, L/H→H, H/L→H, H/H→L. Input thresholds are fixed at VIH ≥ 2.0 V and VIL ≤ 0.8 V under 4.5–5.5 V supply, ensuring robust noise immunity in noisy automotive environments.

FAQ

What is the maximum operating frequency of the 74HCT1G86GV-Q100?

The device does not specify a maximum clock frequency, as it is a combinational logic gate. Its usable toggle rate is limited by propagation delay and load capacitance: at 4.5 V and 50 pF, tpd = 13 ns (typ), supporting signal transitions up to ~38 MHz in ideal conditions. Real-world frequency depends on fan-out, trace capacitance, and supply stability.

Can the 74HCT1G86GV-Q100 operate at 3.3 V supply?

No - the 74HCT1G86GV-Q100 is specified only for 4.5–5.5 V operation per its recommended conditions. At 3.3 V, input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) remain valid, but VOH/VOL performance degrades outside spec, and AEC-Q100 qualification does not cover this voltage. Use 74HC1G86GV-Q100 for 2.0–6.0 V operation.

Is the SC-74A (SOT753) package RoHS and REACH compliant?

Yes - Nexperia confirms full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 for the 74HCT1G86GV-Q100 in SOT753 packaging, including exemption 7a for lead in high-melting-temperature type solders. Full material declarations are available via Nexperia's Product Change Notification portal.

How does the input clamp diode affect external resistor sizing?

When interfacing to voltages > VCC, the internal clamp diode conducts when VIN exceeds VCC + 0.5 V. To limit IIK to ±20 mA max, select a series resistor R ≥ (VIN_max − VCC − 0.5 V) / 20 mA. For example, with VIN_max = 12 V and VCC = 4.5 V, R ≥ (12 − 4.5 − 0.5) / 0.02 = 350 Ω minimum.
