74HCT2G86DP-Q100H

Overview

The Nexperia 74HCT2G86DP-Q100H is a dual 2-input EXCLUSIVE-OR gate in the 74HCT logic family, housed in an SOT505-2 (TSSOP8) package. 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 and includes internal clamp diodes for overvoltage interfacing. It meets AEC-Q100 Grade 1 qualification for automotive use, with ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay is typically 11 ns at 4.5 V.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Dual 2-input EXCLUSIVE-OR logic function with CMOS low power dissipation
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Input clamp diodes enable current limiting resistors for interfacing voltages above VCC

Applications

• Automotive electronic systems requiring qualified logic components
• Mixed-signal circuits utilizing TTL-level input compatibility
• Digital signal processing applications needing exclusive-OR functionality

Procurement Notes

Verify the specific ordering suffix DP corresponds to the TSSOP8 package variant required for your design. Confirm that the H suffix indicates halogen-free status if environmental compliance is mandatory. Ensure the procurement documentation references the latest Rev. 3 datasheet dated November 28, 2023, to guarantee alignment with current electrical specifications and marking codes.

Selection Notes

Select this component when a dual XOR gate is needed with TTL-compatible input thresholds in a compact surface-mount package. The HCT series ensures direct interface with standard TTL logic outputs without level shifting. Consider the wide operating temperature range and automotive qualification if the application environment demands high reliability under thermal stress or vibration.

Part Context

This part belongs to the Nexperia 74HCT2G86-Q100 family of dual 2-input EXCLUSIVE-OR gates. It shares functional characteristics with the HC variant but utilizes HCT input levels for TTL compatibility. The product line is designed for general-purpose digital applications, with specific variants available in different packages such as VSSOP8 to suit various PCB layout constraints.

Replacement Considerations

Direct substitutes include the 74HC2G86DP-Q100H, though it requires CMOS-level inputs rather than TTL. Other compatible parts within the same family may offer different package options like VSSOP8, but verify pinout and electrical parameters match the original design requirements before substitution.

FAQ

What is the maximum supply voltage for the 74HCT2G86DP-Q100H?

The recommended operating conditions specify a maximum supply voltage (VCC) of 5.5 V for the HCT variant.

Does the device support input voltages higher than VCC?

Yes, the inputs include clamp diodes, allowing the use of current-limiting resistors to interface with voltages exceeding VCC.
