74HC1G04GW,125

Overview

The Nexperia 74HC1G04GW,125 is a single inverter integrated circuit manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS input switching levels. The device utilizes a TSSOP5 plastic thin shrink small outline package (SOT353-1) with five leads and a body width of 1.25 mm. It provides high noise immunity, low power dissipation, and balanced propagation delays. Static characteristics include an input leakage current maximum of 1.0 μA at 6.0 V and a supply current maximum of 20 μA at 6.0 V. Dynamic performance specifies a maximum propagation delay of 135 ns at 2.0 V with 50 pF load capacitance, and 27 ns at 4.5 V with 50 pF load capacitance.

Feature Summary

• Features overvoltage tolerant inputs equipped with clamp diodes for interfacing with voltages exceeding VCC using current limiting resistors.
• Provides symmetrical output impedance and balanced propagation delays for consistent signal inversion.
• Includes ESD protection compliant with ANSI/ESDA/JEDEC standards, exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model.

Applications

• Signal inversion in mixed voltage environments
• Logic level translation between different voltage domains
• General-purpose digital logic applications

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the component meets JEDEC compliance requirements for your target application environment. Ensure design safeguards are implemented to prevent operation beyond absolute maximum ratings. Check for any recent Product Change Notifications regarding marking or assembly updates before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel inverter with wide supply voltage flexibility is required. The HC series is appropriate for applications needing CMOS input levels rather than TTL thresholds found in HCT variants. Consider the TSSOP5 package dimensions if board space is constrained. Verify that the operating temperature range aligns with the environmental conditions of the intended deployment scenario.

Part Context

This part belongs to the 74HC1G04 family of single inverters from Nexperia. It shares functional similarities with the 74HCT1G04 but differs in input switching levels, utilizing CMOS thresholds instead of TTL thresholds. The device is designed for general-purpose digital logic applications requiring low power consumption and high noise immunity across a broad voltage spectrum.

Replacement Considerations

The 74HC1G04GV,125 serves as a direct substitute, offering identical electrical characteristics but packaged in SC-74A (SOT753). Designers must verify pinout compatibility and physical footprint differences when transitioning between the TSSOP5 and SC-74A packages.

FAQ

What is the function of the clamp diodes on the inputs?

The clamp diodes allow the use of current limiting resistors to interface the inputs to voltages in excess of VCC, enabling safe operation in mixed voltage environments.

How does the 74HC1G04 differ from the 74HCT1G04?

The 74HC1G04 uses CMOS input switching levels, whereas the 74HCT1G04 uses TTL input switching levels. Both share similar supply voltage ranges and output characteristics.
