74HCT1G00GW-Q100H

Overview

The Nexperia 74HCT1G00GW-Q100H is a single 2-input NAND gate from the 74HCT logic family, housed in a SOT353-1 (TSSOP5) package. 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, clamp diodes on inputs for overvoltage interfacing, and high noise immunity. It meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide operating temperature range specified from -40 °C to +125 °C
• CMOS low power dissipation with symmetrical output impedance
• High noise immunity and balanced propagation delays

Applications

• Automotive electronic systems requiring qualified logic gates
• Signal processing circuits utilizing TTL-to-CMOS level translation
• General-purpose digital logic implementation in harsh environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and marking code alignment. Confirm that the required temperature grade matches the application's thermal constraints. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity. Cross-reference the latest datasheet revision to validate all electrical parameters before final design approval.

Selection Notes

Select this component when a single 2-input NAND function is required in a compact surface-mount package. The HCT series ensures direct compatibility with TTL logic levels while maintaining CMOS performance characteristics. Consider the SOT353-1 package dimensions for PCB layout constraints. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V recommended operating conditions to guarantee proper functionality.

Part Context

This part belongs to the 74HCT1G00-Q100 family of single 2-input NAND gates designed for automotive and industrial use. The 'GW' suffix specifically denotes the TSSOP5 plastic thin shrink small outline package variant. It shares functional similarities with other members of the 74HC/HCT1Gxx-Q100 series but differs in input threshold levels and specific package geometry compared to HC or GV variants.

Replacement Considerations

The 74HC1G00GW-Q100H serves as a pin-compatible alternative within the same package, though it utilizes CMOS input levels rather than TTL levels. Other single-gate NAND options in the 74AUP or 74LVC families may offer different speed or voltage characteristics but require verification of interface compatibility.
