SN74F125NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F125NSR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features four independent non-inverting line drivers. Each output is disabled when the associated output-enable (OE) input is high. The device utilizes an SOP-14 package and supports surface-mount installation. Electrical characteristics include a high-level output current of -15 mA and a low-level output current of 64 mA at 5 V. Propagation delay times are specified between 1.2 ns and 8 ns depending on conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent line drivers with 3-state outputs for driving bus lines or buffering memory address registers.
• Each output is independently controlled by an associated output-enable (OE) input, disabling the output when OE is high.
