74AHCT1G06GW,125

Overview

The Nexperia 74AHCT1G06GW,125 is a high-speed Si-gate CMOS inverter with an open-drain output. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device supports a wide operating temperature range from -40 °C to +125 °C. It is housed in a SOT353-1 (TSSOP5) package with five leads.

Feature Summary

• Open-drain output configuration allows implementation of active-LOW wired-OR or active-HIGH wired-AND functions when connected to other open-drain outputs.
• High noise immunity and low power dissipation characteristics inherent to the Si-gate CMOS technology.
• Robust electrostatic discharge protection exceeding specified thresholds for Human Body Model, Machine Model, and Charged Device Model standards.

Applications

• Digital signal inversion requiring open-drain logic compatibility
• Bus line drivers utilizing wired-OR or wired-AND configurations
• Level shifting interfaces between TTL and CMOS logic families

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure design margins account for the absolute maximum ratings regarding supply voltage and current limits to prevent permanent device damage.

Selection Notes

Select this component when an inverting buffer with an open-drain output is required for wired logic applications. The AHCT variant ensures compatibility with TTL input voltage levels while operating at standard CMOS supply voltages. Consider the thermal derating requirements if ambient temperatures exceed 87.5 °C.

Part Context

This part belongs to the 74AHC(AHCT)1G series of single-gate logic devices manufactured by Nexperia. These components are designed for space-constrained surface-mount applications, offering high performance in minimal footprints. The series provides various logic functions including inverters, buffers, and gates in compact packages like TSSOP and SC-74A.

FAQ

Why is a pull-up resistor required for this device?

Because the output is open-drain, it cannot actively drive the output high. A pull-up resistor to VCC is necessary to establish a logic HIGH level.

What is the difference between the AHC and AHCT variants?

The AHC variant uses CMOS input switching levels and operates from 2.0 V to 5.5 V, whereas the AHCT variant uses TTL input switching levels and operates from 4.5 V to 5.5 V.
