74LVC125AT14-13

Overview

The 74LVC125AT14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the TSSOP-14 package. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V for mixed-voltage environments. The device supports partial power-down applications via I_OFF circuitry, which disables outputs to prevent damaging backflow current. It provides independent output enable control (active low) for each channel.

Feature Summary

• Provides four independent non-inverting buffers with active-low output enable pins
• Supports partial power-down mode operation through integrated I_OFF circuitry
• Inputs accept up to 5.5V, enabling direct interfacing with 3.3V or 5.5V logic systems
• ESD protection exceeds JESD 22 standards for machine, human body, and charged device models

Applications

• Voltage level shifting between different logic families
• General-purpose logic buffering
• Power down signal isolation

Procurement Notes

Verify the specific ordering suffix 'T14' confirms the TSSOP-14 package type rather than SO-14. Confirm that the '-13' suffix corresponds to tape and reel packaging as specified in the manufacturer's ordering information. Ensure compliance requirements such as RoHS and halogen-free status are validated against the latest product documentation before procurement.

Selection Notes

Select this component when designing circuits requiring four buffered channels with high-impedance state control. The wide supply voltage range allows compatibility with various system architectures. The 5.5V input tolerance simplifies interface design in mixed-voltage environments without requiring additional level-shifting components.

Part Context

This part belongs to the 74LVC125A family of quadruple 3-state buffers from Diodes Incorporated. The 'T14' designation specifically identifies the TSSOP-14 surface-mount package variant, distinguishing it from the SO-14 version. The device is part of the broader LVC logic series designed for low-voltage CMOS applications.

Replacement Considerations

The 74LVC125AS14-13 serves as a functional substitute offering identical electrical characteristics but utilizes an SO-14 package instead of TSSOP-14. Verify pinout compatibility and physical footprint differences during replacement planning.
