SN74LVC125ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ANSR is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from 1.65V to 3.6V and features independent output-enable inputs for each buffer. The device accepts input voltages up to 5.5V, allowing compatibility with 5V systems while operating at lower supply voltages. It provides a maximum propagation delay of 4.8ns at 3.3V and supports an operating temperature range from -40°C to 125°C. The component is housed in a 14-pin SOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP-14 package and tape-and-reel carrier configuration. Confirm that the selected variant meets the required thermal resistance and moisture sensitivity level ratings for the intended manufacturing process. Ensure the component status is active production before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing mixed-voltage interfaces requiring 3-state buffering between 3.3V logic and 5V peripherals. The independent OE pins allow precise control over bus directionality. Consider the 5.5V input tolerance as a key advantage for direct interfacing without additional level shifters in legacy system designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffers. It shares functional characteristics with other LVC series devices but is distinct in its specific pinout and 3-state output configuration. The 'ANSR' designation identifies the specific SOP-14 package and reel packaging format offered by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle power-up states?

To ensure the high-impedance state during power up or power down, the OE input should be tied to VCC through a pull-up resistor.

What is the input voltage tolerance?

The inputs can be driven from either 3.3V or 5V devices, accepting voltages up to 5.5V regardless of the VCC supply level.
