SN74LVC1G07DRYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC1G07DRYR is a single buffer/driver from Texas Instruments featuring an open-drain output. It operates within a supply voltage range of 1.65V to 5.5V and accepts input/output voltages up to 5.5V. The device supports bidirectional voltage translation and provides a maximum sink current of 32mA. Propagation delay (tpd) is specified at a maximum of 4.2ns at 3.3V and 4ns at 5V across the -40°C to 125°C temperature range. It includes Ioff circuitry for partial-power-down support, limiting back-drive current to ±10µA. Power consumption is low, with ICC typically at 10µA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Open-drain output configuration enables active-low wired-OR or active-high wired-AND logic functions.
• Integrated Ioff circuitry prevents damaging back-drive currents during partial-power-down or live insertion scenarios.
• Inputs and outputs are tolerant to 5.5V signals while operating on lower supply voltages down to 1.65V.
• High drive capability allows sinking up to 32mA, suitable for direct LED driving or bus interfacing.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm lead finish, material type, and moisture sensitivity level. Ensure the DRY package variant matches the required thermal resistance and pinout specifications for the target PCB layout. Cross-reference RoHS compliance status and peak reflow temperature ratings with assembly process requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting buffer with high sink current capability is required in a compact footprint. The open-drain architecture is essential for implementing wired logic connections or interfacing between buses with different voltage levels. Verify that the 5.5V tolerance meets the interface requirements and that the propagation delay characteristics align with the system's timing constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVC1G series of single-gate logic components manufactured by Texas Instruments. It utilizes CMOS technology to achieve low power consumption while maintaining high-speed performance. The DRY package designation indicates a 6-pin USON form factor with dimensions of 1.45mm x 1.0mm, designed for surface-mount applications requiring minimal board space.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LVC1G07DBVR and SN74LVC1G07DCKR. These variants share identical electrical specifications but utilize different packages such as SOT-23 or SC70. Verify pin compatibility and thermal characteristics when transitioning between package types.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables the internal outputs when VCC is at 0V, preventing damaging current backflow through the device when it is powered down but the system remains energized.

What is the maximum sink current capability?

The device can sink a maximum current of 32mA, making it suitable for driving LEDs or other loads requiring higher current than standard logic gates.
