SN74LVC2G07DSFR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2G07DSFR is a dual buffer and driver with open-drain outputs from the Texas Instruments LVC logic family. It operates within a supply voltage range of 1.65 V to 5.5 V and supports inputs and outputs up to 5.5 V. The device provides a maximum low-level output current of 32 mA and features a propagation delay of 3.7 ns at 3.3 V. It includes Ioff circuitry for partial-power-down support, ensuring back-drive protection. The component is housed in a 6-pin DSF (SON) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DSFR' corresponds to the 6-pin SON package type before procurement. Confirm that the required tape and reel quantity matches the standard 5000-unit spool size defined in the manufacturer's packaging data. Ensure the design accommodates the thermal resistance characteristics associated with this specific NanoFree package variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an open-drain configuration is required for level translation between different voltage domains. It is suitable for applications needing high sink current capabilities exceeding standard CMOS limits. Consider the 5.5 V tolerance feature if interfacing with legacy 5 V systems while powered by lower voltages.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the open-drain output configuration affect signal levels?

The device cannot actively drive the output high; it relies on external pull-up resistors. The output voltage level is determined by the voltage applied to the pull-up resistor, enabling voltage translation.

What is the function of the Ioff circuitry?

The Ioff circuitry automatically disables the outputs when the device is powered down, preventing current from flowing backward through the device into the power rail.
