74HCT1G04GW-Q100H

Overview

The Nexperia 74HCT1G04GW-Q100H is a single inverter within the 74HCT logic family, designed for automotive applications. It operates with a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device is qualified to AEC-Q100 Grade 1 standards and supports an ambient temperature range from -40 °C to +125 °C. It utilizes a TSSOP5 (SOT353-1) package with five leads. Static characteristics include high-level output voltages up to 4.4 V at 4.5 V supply and low leakage currents. Dynamic performance specifies propagation delays of 24 ns maximum at 4.5 V with 50 pF load.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input switching levels for direct interfacing
• Wide operating temperature range extending to +125 °C
• High noise immunity with symmetrical output impedance

Applications

• Automotive electronic systems requiring robust signal inversion
• Mixed-voltage environments utilizing TTL logic interfaces
• Signal conditioning circuits in harsh thermal conditions

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current ordering information to confirm packaging details such as reel or cut tape specifications. Ensure the design accounts for the TSSOP5 package dimensions and thermal derating requirements specified in the datasheet. Confirm that the application voltage strictly adheres to the 4.5 V to 5.5 V recommended operating conditions to maintain valid logic levels and prevent damage.

Selection Notes

Select this component when TTL input compatibility is required alongside automotive reliability standards. The HCT series provides CMOS low power dissipation while maintaining TTL noise margins. Consider the TSSOP5 package size constraints and the need for operation across extended industrial temperatures. Verify that the single-inverter configuration meets the circuit complexity requirements without necessitating multiple devices.

Part Context

This part belongs to the Nexperia 74HCT1G04-Q100 family of single inverters. It shares functional similarities with the 74HC1G04 variant but differs in input threshold levels, supporting TTL logic instead of pure CMOS. The Q100 designation indicates automotive-grade qualification. Other variants in the series may offer different packages like SC-74A or different logic families such as LVC or AUP for varying speed and voltage profiles.

Replacement Considerations

Direct substitutes include the 74HC1G04GW-Q100H, noting the difference between HCT and HC input levels. Verify pinout compatibility and ensure the replacement maintains the required AEC-Q100 qualification if automotive use is intended. Check for equivalent package availability and thermal characteristics.
