74AHC14S14-13

Overview

The 74AHC14S14-13 is a hex inverter with Schmitt trigger inputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs capable of sinking or sourcing 8mA at VCC = 4.5V. The device provides six independent inverters in an SO-14 package, utilizing CMOS technology for low power consumption. Inputs are tolerant to 5.5V, facilitating mixed-voltage environments.

Feature Summary

• Schmitt trigger action at all inputs allows transformation of slow-changing signals into sharply defined output transitions.
• Inputs tolerate up to 5.5V, enabling direct interfacing between 3.3V and 5.5V logic systems.
• ESD protection exceeds JESD 22 standards, including 2000-V Human Body Model and 1000-V Charged Device Model ratings.

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals, hard drives, and CD/DVD ROM drives
• TV, DVD, DVR, and set-top boxes

Procurement Notes

Verify the specific package type required for the design, as the S14 suffix denotes the SO-14 variant. Confirm that the 2500-unit tape and reel packaging aligns with production volume requirements. Ensure input handling meets the 5.5V tolerance specifications if interfacing with higher voltage logic levels.

Selection Notes

Select this component when noise immunity is critical due to the integrated Schmitt trigger functionality. The wide supply voltage range supports diverse system architectures. Verify that the 8mA drive capability satisfies load requirements. Consider the 5.5V input tolerance for seamless integration in mixed-voltage designs without additional level shifting components.

Part Context

This part belongs to the 74AHC14 family of hex inverters. The 'S14' designation specifically identifies the SO-14 surface mount package option. The '-13' suffix indicates the standard 2500-unit tape and reel packaging configuration provided by Diodes Incorporated.

Replacement Considerations

The datasheet does not list official substitute part numbers. Designers should verify pinout compatibility and electrical characteristics against alternative hex inverters from other manufacturers before implementation.
