74LVC07AT14-13

Overview

The Diodes Incorporated 74LVC07AT14-13 is a hex buffer with open-drain outputs in the LVC logic family. 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 sinks 24mA at VCC = 3.3V and includes IOFF circuitry for partial power-down applications. It supports active-low wired-OR or active-high wired-AND functions and provides ESD protection exceeding JESD 22 standards.

Feature Summary

• Provides six independent non-inverting buffers with open-drain outputs
• Supports mixed-voltage operation with 5.5V tolerant inputs
• Includes IOFF circuitry to prevent damaging current backflow during power down
• Capable of implementing active-low wired-OR or active-high wired-AND configurations

Applications

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

Procurement Notes

Verify the specific package code T14 corresponds to the TSSOP-14 form factor required for your PCB layout. Confirm that the -13 suffix indicates tape and reel packaging compatible with standard SMT assembly equipment. Ensure the design accommodates the open-drain output requirement by including appropriate external pull-up resistors for the intended logic high state.

Selection Notes

Select this component when open-drain outputs are necessary for wired-logic implementations or voltage translation. The wide supply range allows compatibility with systems operating from 1.65V up to 5.5V. Verify that the 24mA sink capability meets the load requirements of the driven circuits. Consider the thermal resistance characteristics if multiple gates are actively driving loads simultaneously.

Part Context

This part belongs to the 74LVC07A series of hex buffers with open-drain outputs manufactured by Diodes Incorporated. It is available in SO-14 and TSSOP-14 packages. The AT14 designation specifically identifies the TSSOP-14 package variant, while the AS14 variant utilizes the SO-14 package. Both share identical electrical characteristics and pinouts.

Replacement Considerations

The 74LVC07AS14-13 serves as a direct functional substitute using the SO-14 package instead of TSSOP-14. Other manufacturers' 74LVC07 devices may be compatible if they meet the same electrical specifications and pinout configuration.
