74HCT2G04GV-Q100H

Overview

The Nexperia 74HCT2G04GV-Q100H is a dual inverter integrated circuit designed for automotive applications, qualified to AEC-Q100 Grade 1 standards. 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 utilizes TTL input levels and features balanced propagation delays with high noise immunity. Packaged in the SC-74 (TSOP6) format designated as SOT457, it includes internal clamp diodes on inputs to facilitate interfacing with voltages exceeding VCC using current limiting resistors.

Feature Summary

• Qualified for automotive electronics applications under AEC-Q100 Grade 1 specifications
• Features CMOS low power dissipation combined with high noise immunity
• Includes input clamp diodes enabling interface to voltages above VCC
• Provides symmetrical output impedance and balanced propagation delays

Applications

• Automotive electronic systems requiring robust logic inversion
• Signal level translation between TTL and CMOS domains
• Interface circuits utilizing current limiting resistors for over-voltage protection

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74 package variant during procurement. Confirm that the component meets the required AEC-Q100 Grade 1 qualification status for your target application environment. Ensure compatibility with the specified 4.5 V to 5.5 V supply voltage range and check for any recent product change notices affecting marking or packaging details.

Selection Notes

Select this component when a dual inverter function is required in space-constrained designs due to its small SC-74 footprint. It is appropriate for systems needing TTL-compatible input thresholds while maintaining CMOS performance characteristics. Consider the extended temperature range capability if the operating environment exceeds standard commercial limits. Verify that the ESD protection levels meet the handling requirements of your assembly process.

Part Context

This part belongs to the Nexperia 74HCT2G04-Q100 family of dual inverters. The HCT series specifically denotes TTL input switching levels, distinguishing it from the HC series which uses CMOS levels. The Q100 suffix indicates automotive qualification. The GV suffix identifies the SC-74 plastic surface-mounted package, differentiating it from the GW variant which uses a TSSOP6 package.

Replacement Considerations

The 74HC2G04GV-Q100H serves as a functional alternative but requires verification of input level compatibility, as it utilizes CMOS rather than TTL thresholds. Other variants within the same family may offer different package options such as TSSOP6.
