74HCT2G32DP-Q100H

Overview

The Nexperia 74HCT2G32DP-Q100H is a dual 2-input 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, CMOS low power dissipation, and high noise immunity. Static characteristics include input leakage currents up to ±1.0 μA at -40 °C to +125 °C. Dynamic performance specifies propagation delays with a maximum of 36 ns at 4.5 V across the full temperature range.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL-compatible input levels for direct interfacing with TTL logic systems
• Integrated input clamp diodes enabling interface to voltages exceeding VCC

Applications

• Automotive electronic circuits requiring dual OR logic functions
• Signal routing and selection in vehicle control modules
• Interface circuits between TTL and CMOS logic domains

Procurement Notes

Verify the specific suffix 'H' against the official datasheet, as standard ordering codes list '74HCT2G32DP-Q100'. Confirm package type SOT505-2 (TSSOP8) matches design requirements. Ensure temperature grade aligns with the specified -40 °C to +125 °C range. Check marking code 'T32' for identification. Validate that the supplier provides documentation confirming AEC-Q100 compliance for this exact part number.

Selection Notes

Select this component when TTL-level input compatibility is required alongside automotive reliability standards. The HCT variant ensures proper logic threshold matching with TTL sources, unlike the HC version which uses CMOS levels. The TSSOP8 package offers a compact solution for space-constrained automotive PCB layouts while maintaining thermal performance within the specified operating range.

Part Context

This component belongs to the Nexperia 74HCT2G32-Q100 family of dual 2-input OR gates. It shares functional similarities with the 74HC2G32-Q100 but differs in input voltage thresholds to support TTL interfaces. Both variants are designed for automotive applications and utilize similar packaging options including TSSOP8 and VSSOP8.

Replacement Considerations

The 74HC2G32DP-Q100 serves as a pin-compatible alternative but requires CMOS-level inputs rather than TTL. Verify input voltage compatibility before substitution. Other family members like 74HCT2G32DC-Q100 offer different packaging but identical electrical functionality.
