74HCT1G32GV-Q100H

Overview

The Nexperia 74HCT1G32GV-Q100H is a single 2-input OR gate in the 74HCT logic series, housed in a SC-74A (SOT753) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-level input compatibility, symmetrical output impedance, and high noise immunity. It includes input clamp diodes for interfacing with voltages exceeding VCC and meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input levels ensuring direct interface with standard logic families
• Extended operating temperature range supporting harsh environmental conditions
• Integrated ESD protection meeting JESD standards for robust signal integrity

Applications

• Automotive electronic systems requiring qualified logic components
• Signal routing and data path selection in digital circuits
• Interface modules connecting TTL-based controllers to CMOS peripherals

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A package configuration required for your design. Confirm that the AEC-Q100 Grade 1 qualification aligns with your project's automotive reliability specifications. Ensure the 4.5 V to 5.5 V supply voltage range matches your system power rails before finalizing procurement.

Selection Notes

Select this component when TTL-level inputs are necessary within a CMOS environment. The wide temperature range makes it suitable for under-hood or industrial applications. Consider the SC-74A package size if board space is constrained but through-hole or larger surface-mount options are unavailable. Verify that the propagation delay characteristics meet your timing requirements at the target supply voltage.

Part Context

This part belongs to the 74HCT1G32-Q100 family of single 2-input OR gates. It shares functional similarities with the 74HC1G32-Q100 but differs in input threshold levels, offering TTL compatibility instead of pure CMOS thresholds. The Q100 suffix indicates automotive qualification, distinguishing it from commercial variants like the 74HCT1G32GV,125.

Replacement Considerations

The 74HC1G32GV-Q100H serves as a pin-compatible alternative but utilizes CMOS input levels rather than TTL. For non-automotive applications, the 74HCT1G32GV,125 offers identical electrical performance without the automotive qualification.
