74AHC1G14W5-7

Overview

The 74AHC1G14W5-7 is a single-input Schmitt-trigger inverter from the AHC logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features a standard push-pull output capable of ±8 mA drive current at 5.0V. The device utilizes CMOS technology for low power consumption and includes robust ESD protection exceeding 2000-V Human Body Model standards. It is housed in a SOT-25 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Schmitt trigger input action provides circuit tolerance for slower input rise and fall times
• Standard push-pull output configuration with ±8 mA drive capability at 5.0V
• ESD protection exceeds 2000-V Human Body Model and 200-V Machine Model ratings
• Latch-up performance exceeds 100mA per JESD 78 Class II

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TV, DVD, DVR, and set-top boxes
• Personal navigation/GPS devices and MP3 players

Procurement Notes

Verify the specific ordering suffix W5 corresponds to the SOT-25 package when sourcing this component. Confirm RoHS compliance status and lead-free finish requirements against the latest manufacturer documentation. Ensure that unused inputs are properly tied to VCC or Ground during implementation to maintain specified electrical characteristics and prevent undefined states.

Selection Notes

Select this component for applications requiring noise immunity through Schmitt trigger inputs and operation across a wide voltage range of 2.0V to 5.5V. Consider the AHC family for faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Verify that the SOT-25 package dimensions fit the available PCB real estate and thermal management requirements for the target environment.

Part Context

This part belongs to the 74AHC1G series of single-gate logic ICs produced by Diodes Incorporated under the AHC (Advanced High-Speed CMOS) family. The '1G' designation indicates a single gate configuration, while '14' specifies the inverter function with Schmitt trigger inputs. The W5 suffix identifies the SOT-25 surface-mount package variant, distinguishing it from other package options like SOT-353.

Replacement Considerations

Cross-reference with 74AHCT1G14W5-7 for compatible 5V-only logic level interfaces. Evaluate 74LVC1G14W5-7 if lower minimum supply voltage operation below 2.0V is required.
