SN74ABT125NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT125NS is a quadruple bus buffer gate with three-state outputs manufactured by Texas Instruments. It belongs to the ABT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features four independent channels with non-inverting polarity and single-ended inputs. It utilizes an SOIC-14 surface-mount package, measuring 8.65 mm in length, 3.9 mm in width, and 1.5 mm in height. Electrical characteristics include a maximum high-level output current of -32 mA and a low-level output current of 64 mA. Propagation delay is specified at 4.6 ns under a 50 pF load condition at 5 V. The component supports an operating temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix designation against official Texas Instruments documentation, as generic model numbers often omit critical packaging or temperature grade indicators. Confirm RoHS compliance status and moisture sensitivity level requirements specific to the manufacturing batch. Ensure the selected variant matches the required pin configuration and thermal performance specifications for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 5 V operation with moderate speed and high drive capability. Compare propagation delay and output current specifications against alternative logic families such as F or LVTH if lower power consumption or different voltage levels are required. Verify that the SOIC-14 package dimensions fit the available PCB footprint and assembly constraints.
