74LX1G125CTR

Buffers, Drivers, Receivers, Transceivers Overview

The 74LX1G125CTR is a single bus buffer manufactured by STMicroelectronics, utilizing sub-micron silicon gate and double-layer metal wiring C2MOS technology. It operates within a wide supply voltage range of 1.65V to 5.5V, with data retention at 1.2V. The device features 3-state control input G, which must be set HIGH to place the output into a high impedance state. It provides power down protection on all inputs and outputs, accepting 0 to 7V on inputs regardless of the supply voltage. The component is housed in an SOT323-5L package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact ordering code against the datasheet, as suffixes indicate specific packaging options. Confirm that the SOT323-5L package matches your board layout requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure the component meets the operating temperature range specified for your application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different voltage domains, specifically from 5V to lower voltages like 3V or 1.8V. Consider its low power dissipation characteristics for battery-powered equipment. Verify that the propagation delay and output current capabilities meet the speed and drive requirements of your specific circuit design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LX series of logic integrated circuits, designed for low-voltage applications. It is functionally compatible with other 74-series logic devices but optimized for lower power consumption and wider voltage operation ranges. The single buffer configuration makes it suitable for simple signal routing and level shifting tasks in compact electronic designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements from other manufacturers that offer the same SOT323-5L package and logical functionality. Ensure any substitute maintains the 5V tolerance and power-down protection features. Verify that the replacement's electrical specifications, such as propagation delay and output current, are equal to or better than the original.
