Nexperia USA Inc. 74HCT1G86GW-Q100H

Overview

74HCT1G86GW-Q100 from Nexperia is a single 2-input EXCLUSIVE-OR gate in TSSOP5 (SOT353-1) package, designed for automotive signal-level logic comparison and data path control. It operates from 4.5 V to 5.5 V, delivers TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), and achieves 13 ns typical propagation delay at VCC = 4.5 V with CL = 50 pF - enabling precise timing in CAN/LIN bus interface arbitration and sensor signal conditioning circuits.

For engineers reviewing the 74HCT1G86GW-Q100 datasheet, 74HCT1G86GW-Q100 pinout, 74HCT1G86GW-Q100 application, or 74HCT1G86GW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), symmetrical output impedance, latch-up immunity (>100 mA), and HBM ESD rating exceeding 2000 V - critical for under-hood ECUs and ADAS domain controllers.

Technical Context

This device implements standard XOR logic (Y = A ⊕ B) using silicon-gate CMOS technology with TTL-level input compatibility. Its internal structure includes input clamp diodes enabling safe interfacing to voltages beyond VCC when used with current-limiting resistors, and it features balanced tPLH/tPHL propagation delays ensuring minimal duty-cycle distortion in clocked data paths.

The logic gate supports rail-to-rail output swing with VOH ≥ 4.13 V and VOL ≤ 0.33 V at IO = ±2.0 mA (VCC = 4.5 V), and maintains static input leakage < 1.0 μA across temperature. Its power dissipation capacitance CPD is 23 pF, directly determining dynamic power consumption in high-frequency switching applications.

FAQ

What is the maximum operating frequency supported by the 74HCT1G86GW-Q100?

The device does not specify a maximum clock frequency, but its 13 ns typical propagation delay at VCC = 4.5 V and CL = 50 pF implies reliable operation up to approximately 30 MHz for toggle-rate-limited applications. Actual usable frequency depends on load capacitance, supply stability, and PCB layout - measured tPLH/tPHL balance ensures minimal jitter in clock-derived signals.

Can the 74HCT1G86GW-Q100 interface directly with 3.3 V microcontrollers?

No - its TTL-compatible inputs require VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V, making it incompatible with 3.3 V logic without level translation. Driving it from a 3.3 V MCU output risks marginal VIH recognition; conversely, its 5 V outputs exceed 3.3 V I/O absolute maximum ratings and require clamping or resistive division.

Does this device support hot-swap or live-insertion in automotive modules?

No - it lacks explicit hot-swap protection features such as power-on reset, undervoltage lockout, or slew-rate controlled outputs. The input clamp diodes provide limited overvoltage tolerance (up to VCC + 0.5 V), but uncontrolled insertion into a powered backplane may cause transient currents exceeding ±20 mA clamping limits and induce system-level faults.

How does the TSSOP5 package affect thermal performance in sealed ECU enclosures?

The SOT353-1 package has a thermal resistance θJA of ~220 K/W (typical), with linear derating of 3.3 mW/K above 74 °C. In sealed enclosures reaching 105 °C ambient, total power dissipation must remain below ~170 mW to avoid exceeding junction temperature limits - achievable given its 20 μA ICC and 23 pF CPD, resulting in <1 mW static + <0.5 mW dynamic power at 1 MHz.
