SN74LVTH273DWRE4

Flip Flops Overview

The SN74LVTH273DWRE4 is an octal D-type flip-flop manufactured by Texas Instruments, featuring a positive-edge trigger mechanism and an asynchronous clear input. It utilizes LVTH (Low-Voltage CMOS with TTL-compatible inputs) technology to ensure compatibility with both 5V and 3.3V systems. The device is housed in a 20-SOIC package and operates within a supply voltage range of 2.0 V to 5.5 V. It supports a wide operating temperature range from -40°C to +85°C, making it suitable for industrial applications requiring robust logic control.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggering ensures data capture occurs at the rising edge of the clock signal
• Asynchronous clear function allows immediate reset of all outputs regardless of clock state
• TTL-compatible inputs facilitate direct interfacing with standard logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in microprocessor systems
• Buffering and latching digital signals in communication interfaces
• Control logic for memory address registers

Flip Flops Procurement Notes

Verify that the specific part number includes the RE4 suffix, which indicates compliance with RoHS standards and restricts hazardous substances. Confirm the SOIC-20 package dimensions match the target PCB footprint. Ensure the supply voltage requirements align with the system's 2.0 V to 5.5 V operational range before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems that require interface between 5V and 3.3V logic domains due to its TTL-compatible input characteristics. Consider the LVTH series for applications needing faster switching speeds than standard HC logic while maintaining low power consumption. Evaluate the SOIC-20 package size against available board space constraints during the initial schematic design phase.
