SN74LVC2G07DCKRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2G07DCKRE4 is a dual non-inverting buffer and driver with open-drain outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum low-level output current of 32 mA. The device supports partial-power-down applications via Ioff circuitry, which disables outputs to prevent backflow. It includes high ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Propagation delay is typically 3.7 ns at 3.3 V. The component is housed in a 6-pin SC-70 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant specifications as defined in the manufacturer's documentation. Confirm that the SC-70 package dimensions align with the target PCB footprint requirements. Ensure the design accounts for the open-drain nature of the outputs, requiring external pull-up resistors to establish high logic levels.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an application requires driving loads with higher current than standard CMOS gates provide, specifically utilizing open-drain topology. It is suitable for interfacing between systems operating at different voltage levels due to its 5.5 V tolerant inputs and outputs. Consider the NanoFree packaging for space-constrained designs where minimal board area is critical.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the Ioff feature function?

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

Can this device be used for voltage translation?

Yes, because the inputs and open-drain outputs accept voltages up to 5.5 V, it supports both up-translation and down-translation between different voltage domains.
