74AHCT1G04GV,125

Overview

The Nexperia 74AHCT1G04GV,125 is a single inverter within the 74AHCT logic family. It operates with TTL input switching levels and a supply voltage range of 4.5 V to 5.5 V. The device features overvoltage tolerant inputs up to 5.5 V, high noise immunity, and CMOS low power dissipation. It provides symmetrical output impedance and balanced propagation delays. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance complies with JESD 78 Class II Level A. The component is specified for operation from -40 °C to +125 °C and utilizes a 5-lead SC-74A (SOT753) surface-mount package.

Feature Summary

• TTL-compatible input switching levels for direct interfacing with Transistor-Transistor Logic systems
• Overvoltage tolerant inputs allowing safe operation in mixed-voltage environments
• Balanced propagation delays and symmetrical output impedance for signal integrity

Applications

• Signal inversion in digital logic circuits
• Voltage translation between mixed voltage domains
• Buffering and line driving applications requiring single-channel inversion

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the SC-74A (SOT753) package variant during procurement. Confirm that the application environment remains within the recommended operating conditions, specifically the 4.5 V to 5.5 V supply voltage range. Ensure design safeguards account for the absolute maximum ratings to prevent permanent damage from stress events exceeding the specified limits.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed CMOS performance characteristics. The AHCT series is suitable for designs needing overvoltage tolerance on inputs while maintaining standard CMOS output drive capabilities. Consider the SC-74A package dimensions if space-constrained surface-mount assembly is necessary. Verify that the single-inverter configuration meets the circuit requirements without necessitating unused gate handling.

Part Context

This component belongs to the Nexperia 74AHCT1G04 series, which includes variants in TSSOP5, XSON6, and XSON5 packages. The GV suffix specifically denotes the SC-74A plastic surface-mounted package with five leads. The series shares functional similarities with the 74AHC1G04 but differs in input switching level specifications, catering to distinct logic interface requirements.

Replacement Considerations

Direct substitutes include other 74AHCT1G04 variants such as 74AHCT1G04GW or 74AHCT1G04GM, provided the package type matches the PCB footprint. Cross-family replacements like 74HC1G04 require verification of input voltage compatibility due to differing switching thresholds.
