74LV273D,112

Overview

The 74LV273D,112 is an octal D-type flip-flop manufactured by Nexperia. It features eight positive-edge triggered D-type flip-flops with a common clock and a master reset input. The device operates within a supply voltage range of 1.2 V to 3.6 V. It utilizes a 20-pin SOIC package for surface-mount installation. The component supports a maximum propagation delay of 6 ns at 3.3 V and provides high-level output currents up to -24 mA. It functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Contains eight independent positive-edge triggered D-type flip-flops sharing a single clock signal
• Includes a dedicated master reset input for synchronous or asynchronous clearing of outputs
• Supports low-voltage operation with a wide power supply range extending down to 1.2 V
• Provides non-inverting outputs capable of driving significant load currents

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage in digital systems
• Data buffering between logic domains
• Timing synchronization and edge detection applications

Procurement Notes

Verify the specific manufacturer designation as sources may list this part under Nexperia rather than NXP USA Inc., reflecting corporate restructuring. Confirm the suffix 112 corresponds to tube packaging if required. Check current availability status as some distributors indicate limited stock or end-of-life conditions for this specific variant. Ensure compatibility with the target PCB footprint for the 20-SOIC package before ordering.

Selection Notes

Select this component when an octal register with a common clock is required for low-voltage logic interfaces. Compare against the 74LVC273 series for faster switching speeds if the application demands higher performance. Verify that the 1.2 V minimum supply voltage meets the system requirements, as some similar devices require higher voltages. Ensure the 20-SOIC package dimensions fit the available board space constraints.

Part Context

This part belongs to the 74LV logic family, designed for low-voltage applications. It serves as an octal version of the standard D-type flip-flop architecture. The device is functionally similar to other octal registers but optimized for lower power consumption compared to older CMOS families. It is widely used in consumer electronics and industrial control systems requiring reliable data storage.

Replacement Considerations

The 74LV273D,118 is a direct replacement offering identical electrical characteristics but packaged in tape and reel format instead of tubes. Other compatible parts include the SN74LV273ADBR from Texas Instruments and the 74LVC273D from Nexperia, though voltage ranges and speed specifications should be verified for exact interchangeability.
