74LVC06AT14-13

Overview

The 74LVC06AT14-13 is a hex inverter with open-drain outputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and features inputs tolerant to 5.5V, enabling mixed-voltage applications. The device supports partial power-down modes via I_OFF circuitry to prevent backflow current. It sinks 24mA at VCC = 3.3V and includes ESD protection exceeding JESD 22 standards. Available in SO-14 and TSSOP-14 packages, it is fully RoHS compliant and halogen-free.

Feature Summary

• Hex inverters with open-drain outputs for active-low wired-OR or active-high wired-AND functions
• Inputs accept up to 5.5V, allowing direct translation from 3.3V or 5.5V sources
• I_OFF circuitry disables outputs during partial power-down to prevent damaging backflow
• ESD protection exceeds JESD 22 requirements across machine, human body, and charged device models

Applications

• Voltage level shifting between different logic domains
• General-purpose logic inversion in mixed-voltage environments
• Power down signal isolation to protect downstream components

Procurement Notes

Verify the specific package suffix (S14 for SO-14 or T14 for TSSOP-14) when ordering, as the base part number covers both. Confirm compliance with RoHS 3 and REACH directives if required by your manufacturing standards. Ensure input pins are tied to VCC or Ground when unused to maintain stable operation. Check the latest datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing the design.

Selection Notes

Select this component when open-drain output capability is required for wired-logic configurations or driving loads above the supply voltage. The wide input tolerance makes it suitable for interfacing with legacy 5V systems while operating at lower voltages. Consider the TSSOP-14 package for higher pin density applications where space is limited compared to the standard SO-14 footprint.

Part Context

This part belongs to the 74LVC family, designed for low-voltage CMOS applications. It complements other LVC series buffers and drivers by providing inverted signals with open-drain outputs. The 'A' designation indicates an updated version with enhanced specifications compared to earlier iterations. It is commonly used alongside non-inverting buffers like the 74LVC126 for complete signal conditioning needs.

Replacement Considerations

Direct substitutes include the 74LVC06AS14-13 (SO-14 package) and 74LVC06AT14-13 (TSSOP-14 package). Cross-brand equivalents such as Nexperia's 74LVC06A variants may be considered if electrical parameters match exactly. Verify pinout compatibility and ensure the replacement supports the same 5.5V input tolerance and open-drain functionality.
