74HCT1G02GW-Q100,1

Overview

The Nexperia 74HCT1G02GW-Q100,1 is a single 2-input NOR gate from the 74HCT1G series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-level input compatibility and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. It is packaged in a TSSOP5 (SOT353-1) plastic thin shrink small outline package with five leads.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standards
• TTL-level input logic compatibility for direct interface with TTL devices
• High noise immunity and symmetrical output impedance characteristics
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model

Applications

• Automotive electronic systems requiring Grade 1 qualified logic components
• Mixed voltage environments utilizing current limiting resistors with clamp diodes
• General-purpose digital logic processing in automotive-grade applications

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm that the procurement channel provides valid traceability for AEC-Q100 Grade 1 automotive qualification requirements. Cross-reference the marking code TB with the datasheet to validate authenticity upon receipt.

Selection Notes

Select this component when TTL-level input thresholds are required at 5 V operation. Ensure the application environment remains within the specified -40 °C to +125 °C operating range. Verify that the TSSOP5 package dimensions align with the PCB footprint constraints. Consider the CMOS low power dissipation benefits for battery-sensitive automotive subsystems.

Part Context

This part belongs to the 74HCT1G-Q100 family of single logic gates designed for automotive use. It shares the same physical package and pinout as the 74HC1G02 variant but differs in input threshold levels to support TTL logic families. The Q100 suffix indicates automotive qualification, distinguishing it from standard commercial grade parts.

Replacement Considerations

The 74HC1G02GW-Q100 serves as a functional substitute if CMOS-level input thresholds are acceptable instead of TTL levels. Both share identical pinouts and packaging.
