74AHCT1G06GW,165

Overview

The 74AHCT1G06GW,165 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 wired-OR or wired-AND functions when connected to other open-drain outputs. It includes ESD protection exceeding 2000 V (HBM) and 200 V (MM). Operating temperatures range from -40 °C to +125 °C.

Feature Summary

• Open-drain output configuration enabling active-LOW wired-OR or active-HIGH wired-AND logic implementation
• TTL-compatible input switching levels for direct interface with standard digital logic families
• High noise immunity and low power dissipation characteristics inherent to the Si-gate CMOS technology

Applications

• Digital signal inversion in systems requiring open-drain output compatibility
• Bus line drivers where multiple devices share a common data line via wired-logic
• Level shifting interfaces between TTL and CMOS domains operating at 5 V

Procurement Notes

Verify the component marking code 'CR' on the TSSOP5 package to confirm authenticity. Ensure the supply voltage remains strictly within the 4.5 V to 5.5 V range to prevent damage. Confirm that the application design includes necessary pull-up resistors to establish valid logic HIGH states at the open-drain output.

Selection Notes

Select this component when TTL-level inputs are required alongside an open-drain output capability. It is suitable for applications needing wired-logic functionality without additional external gates. Verify that the load capacitance and propagation delay specifications meet the system timing requirements under the intended operating temperature conditions.

Part Context

This part belongs to the 74AHC(AHCT)1G06 family of single inverters. It shares functional similarities with the 74AHC1G06 but differs in input threshold voltages. The GW suffix indicates the TSSOP5 plastic thin shrink small outline package. It serves as a fundamental building block for digital logic circuits requiring signal inversion and bus sharing capabilities.

Replacement Considerations

The 74AHC1G06GW is a compatible alternative if CMOS input thresholds are acceptable instead of TTL levels. Other single inverters from the same family may be considered if pinout and package dimensions match the existing layout constraints.
