74HCT2G86DC-Q100H

Overview

The Nexperia 74HCT2G86DC-Q100 is a dual 2-input EXCLUSIVE-OR gate qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level inputs, clamp diodes for high-voltage interfacing, and low power CMOS dissipation. Static characteristics include input leakage currents up to ±1.0 μA at -40 °C to +125 °C. Dynamic performance specifies propagation delays up to 48 ns at 4.5 V across the full temperature range.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL-level input compatibility for direct interface with transistor-transistor logic systems
• Integrated input clamp diodes enabling current limiting resistor usage for voltages exceeding VCC

Applications

• Automotive electronic circuits requiring exclusive-OR logic functions
• Systems utilizing TTL-level digital signal processing
• Applications demanding operation across extended industrial temperature ranges

Procurement Notes

Verify the specific ordering suffix DC corresponds to the VSSOP8 package (SOT765-1) when sourcing. Confirm that the H suffix indicates high-temperature reliability suitable for the required operational environment. Ensure design specifications align with the recommended operating conditions provided in the official datasheet to maintain compliance with automotive quality standards.

Selection Notes

Select this component when TTL-level input thresholds are required rather than CMOS levels. The VSSOP8 package offers a compact footprint suitable for space-constrained designs. Verify that the supply voltage remains within the 4.5 V to 5.5 V range to ensure proper logic level interpretation and dynamic performance characteristics as defined by the manufacturer.

Part Context

This part belongs to the 74HCT2G86-Q100 family of dual 2-input EXCLUSIVE-OR gates. It shares functional architecture with the HC variant but differs in input threshold specifications. The DC suffix specifically denotes the very thin shrink small outline plastic package. This family is designed for robust performance in environments subject to electrical noise and wide thermal variations.

Replacement Considerations

The 74HC2G86DC-Q100 serves as a pin-compatible alternative if CMOS-level inputs are acceptable instead of TTL levels. No other direct substitutes are documented in the provided source material.
