Nexperia USA Inc. 74HC2G86DC-Q100H

Overview

74HC2G86DC-Q100 from Nexperia is a dual 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, propagation delay as low as 9.0 ns at VCC = 6.0 V, and input clamp diodes enabling overvoltage-tolerant interfacing in automotive body control modules.

For engineers reviewing the 74HC2G86DC-Q100 datasheet, 74HC2G86DC-Q100 pinout, 74HC2G86DC-Q100 application, or 74HC2G86DC-Q100 equivalent, this device supports logic-level translation, parity generation, and signal comparison in safety-critical automotive subsystems where latch-up immunity (>100 mA), high noise immunity, and stable operation across extended temperature are mandatory.

Technical Context

This dual XOR gate implements two independent CMOS logic functions with TTL-compatible input thresholds only in the 74HCT variant; the 74HC2G86DC-Q100 uses pure CMOS input levels (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC). Each gate features symmetrical propagation delays (tPLH ≈ tPHL) and matched transition times (tTLH ≈ tTHL), ensuring deterministic timing behavior in synchronous data paths.

Input clamp diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors, and the device complies with JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards. ESD robustness meets HBM >2000 V and CDM >1000 V per JS-001/JS-002.

FAQ

What is the maximum clock frequency supported by the 74HC2G86DC-Q100?

The 74HC2G86DC-Q100 is a combinational logic gate, not a clocked device, so it has no defined clock frequency. Its usable toggle rate is determined by propagation delay and load capacitance: at VCC = 6.0 V and CL = 50 pF, maximum reliable toggle rate is approximately 25 MHz (based on tpd = 9.0 ns and tt = 13 ns).

Can the 74HC2G86DC-Q100 drive an LED directly?

No - its output current rating is ±4.0 mA at VCC = 4.5 V, insufficient for most visible LEDs requiring ≥5 mA at ≥1.8 V forward voltage. It can drive high-efficiency indicator LEDs only with series resistance limiting current to ≤4 mA, but dedicated LED drivers are recommended for brightness control and reliability.

Does the 74HC2G86DC-Q100 support mixed-voltage operation (e.g., 3.3 V inputs with 5.0 V supply)?

Yes - its CMOS inputs are overvoltage-tolerant up to VCC + 0.5 V when used with current-limiting resistors. With VCC = 5.0 V, 3.3 V logic inputs are fully compatible and meet VIH/VIL thresholds; however, outputs swing rail-to-rail (0–5 V), requiring level translation for 3.3 V receivers.

How does the 74HC2G86DC-Q100 differ from the 74HC2G86DP-Q100?

The 74HC2G86DC-Q100 uses the VSSOP8 package (SOT765-1, 2.3 mm body width), while the 74HC2G86DP-Q100 uses TSSOP8 (SOT505-2, 3.0 mm body width). Both share identical electrical specifications, pinout, and AEC-Q100 qualification; the difference is purely mechanical - DC offers higher board density, DP offers easier manual soldering and test probing.
