SN74AUC1G06DBVRE4

Overview

The SN74AUC1G06DBVRE4 is a single inverter buffer/driver with an open-drain output, manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.8-V operation. The device features low power consumption with a maximum quiescent current of 10 μA and supports partial-power-down mode via Ioff circuitry. It provides ±8-mA output drive at 1.8 V and exhibits a maximum propagation delay of 2.5 ns at 1.8 V. The component is housed in a SOT-23 (DBV) package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Open-drain output configuration enables active-low wired-OR or active-high wired-AND logic implementation.
• Integrated Ioff circuitry disables outputs to prevent damaging backflow during partial-power-down states.
• High ESD protection performance exceeding JESD 22 standards for human-body, machine-model, and charged-device models.

Applications

• Mixed-mode signal applications supporting 3.6-V I/O interfaces
• Partial-power-down system designs requiring output isolation
• Low-voltage digital logic inversion and buffering

Procurement Notes

Verify the ordering suffix 'E4' corresponds to the specific RoHS-compliant variant and lead finish details listed in the Package Option Addendum. Confirm that the DBV package designation matches the required SOT-23 footprint and pinout for your PCB layout. Ensure the procurement channel sources production data parts rather than preproduction prototypes to guarantee full specification compliance and standard warranty coverage.

Selection Notes

Select this component when a single-channel inverting function with open-drain capability is required for sub-1-V to 2.7-V logic levels. The AUC series offers faster switching speeds compared to legacy families while maintaining low power consumption. Consider the SOT-23 package size constraints and verify that the 10-μA maximum quiescent current meets the system's standby power budget requirements.

Part Context

This device belongs to the SN74AUC1Gxx family of Little Logic devices from Texas Instruments. These components utilize NanoStar and NanoFree packaging technologies to provide high-density integration in minimal footprints. The AUC series is designed specifically for low-voltage portable and battery-operated applications requiring high speed and low power dissipation.

Replacement Considerations

SN74AUC1G06DBVR: Identical functional device in the same SOT-23 package without the E4 suffix.

FAQ

Can multiple SN74AUC1G06DBVRE4 outputs be connected together?

Yes, the open-drain output allows connection to other open-drain outputs to implement wired-OR or wired-AND functions.

How does the device handle partial-power-down conditions?

The integrated Ioff circuitry automatically disables the outputs when powered down, preventing damaging current backflow through the device.
