SN74LV4T125RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV4T125RGYR is a single-supply quad bus buffer gate manufactured by Texas Instruments. It operates within a wide voltage range of 1.6 V to 5.5 V, supporting logic levels for 1.8 V, 2.5 V, 3.3 V, and 5 V CMOS applications. The device features non-inverting outputs with three-state capability and low input thresholds compatible with 1.8 V inputs at 3.3 V supply. It provides an output drive current of 8 mA to minimize signal reflections. The component is housed in a 14-pin VQFN package (RGY) measuring 3.5 mm x 3.5 mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RGYR confirms the 14-VQFN package and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer datasheet for exact pinout and electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring flexible voltage translation across multiple standard logic levels. It is suitable for applications needing reduced signal integrity issues due to its controlled drive strength. Consider the VQFN package size for space-constrained layouts. Verify that the single-supply architecture aligns with your power distribution design constraints.
