74AHC125T14-13

Overview

The 74AHC125T14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the AHC logic series. It features four independent non-inverting buffers with separate active-low data enable pins (OE). The device operates within a supply voltage range of 2.0V to 5.5V and provides outputs capable of sinking or sourcing 8mA at VCC = 4.5V. Inputs are tolerant to 5.5V, facilitating mixed-voltage environments. It utilizes TSSOP-14 packaging and includes Schmitt trigger action at all inputs.

Feature Summary

• Provides four independent non-inverting buffer gates with separate active-low output enable control
• Features Schmitt trigger action at all inputs for improved noise immunity
• Inputs tolerate up to 5.5V, enabling compatibility in mixed-voltage systems

Applications

• General purpose logic applications
• 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 matches the design requirements, as the 74AHC125 family is available in both SO-14 and TSSOP-14 configurations. Confirm that the active-low enable logic aligns with the system control signals. Ensure the operating temperature range meets the environmental specifications of the target application.

Selection Notes

Select this component when high-speed buffering with low power consumption is required. The wide supply voltage range supports various digital logic families. Verify that the 8mA drive capability is sufficient for the connected loads. Consider the input voltage tolerance if interfacing with 5.5V signals while powered at lower voltages.

Part Context

This part belongs to the 74AHC125 family of quadruple 3-state buffers from Diodes Incorporated. It shares functional similarities with other members like the 74AHC126 but differs in enable pin polarity. The T14 suffix specifically denotes the TSSOP-14 surface-mount package variant.

Replacement Considerations

Check for equivalent parts such as the 74AHC126T14-13, noting the difference in enable pin logic levels. Verify pinout compatibility and electrical characteristics before substitution.
