74HCT1G32GW-Q100H

Overview

The Nexperia 74HCT1G32GW-Q100H is a single 2-input OR gate in the 74HCT series, housed in a 5-TSSOP (SOT353-1) 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-compatible input levels with a maximum propagation delay of 27 ns at 4.5 V with a 50 pF load. It includes input clamp diodes for interfacing with voltages exceeding VCC and meets AEC-Q100 Grade 1 qualification standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• TTL-level input compatibility for direct interfacing with standard logic families
• Extended high-temperature operation capability up to +125 °C
• Integrated input clamp diodes enabling safe interface to voltages above VCC

Applications

• Automotive electronic systems requiring robust logic gating
• High-temperature industrial control circuits
• Signal routing and logic combination in 5V digital systems

Procurement Notes

Verify that the specific order suffix matches the required packaging format, as the datasheet lists multiple package options including TSSOP5, SC-74A, and XSON5. Confirm the component status remains active and check for any recent Product Change Notifications regarding marking codes or assembly sources before finalizing procurement specifications.

Selection Notes

Select this component when a single 2-input OR function is required in automotive or high-temperature environments. Ensure the system operates strictly within the 4.5 V to 5.5 V supply voltage range. Verify that the TTL input thresholds align with the driving source logic levels, as HC variants offer different input characteristics.

Part Context

This part belongs to the 74HCT1G32-Q100 family of single-function gates. It shares functional similarities with other members like the 74HC1G32GW-Q100H but differs in input threshold specifications. The 'GW' designation specifically identifies the TSSOP5 plastic thin shrink small outline package variant.

Replacement Considerations

The 74HC1G32GW-Q100H serves as a pin-compatible alternative within the same package, though it utilizes CMOS input levels rather than TTL levels.
