SN74LVC1G07DBVTG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC1G07DBVTG4 is a single buffer/driver from the LVC logic family, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65V to 5.5V and features an open-drain output capable of sinking up to 32mA. The device supports bidirectional voltage translation between 5.5V tolerant inputs/outputs and lower VCC levels. Propagation delay is specified at a maximum of 4.2ns at 3.3V and 3.5ns at 5V. It utilizes a DBV (SOT-23) package with five pins.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Open-drain output configuration enables active-low wired-OR or active-high wired-AND logic functions.
• Ioff circuitry prevents back-drive current when the device is powered down, supporting live insertion.
• Inputs and outputs are tolerant to voltages up to 5.5V regardless of the VCC level.
• ESD protection performance exceeds JESD 22 requirements for human-body, machine, and charged-device models.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to lead-free and RoHS-compliant manufacturing standards as defined in the manufacturer's documentation. Confirm that the DBV package variant matches the required footprint dimensions and thermal characteristics for the target PCB layout. Ensure compatibility with the intended operating temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel non-inverting buffer with high sink current capability is required. The open-drain architecture is suitable for interfacing with different voltage domains or implementing bus arbitration. Consider the propagation delay specifications relative to the system clock speed and ensure the load capacitance remains within recommended limits to maintain signal integrity.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs when VCC is at 0V, preventing damaging current backflow through the device during partial-power-down scenarios or live insertion events.

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 drive currents compared to standard logic buffers.
