SN74HC273DWRG4

Flip Flops Overview

The SN74HC273DWRG4 is an octal D-type flip-flop with a clear input, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 20-SOIC package. The device features a propagation delay of 160 ns, with high-level output current of -5.2 mA and low-level output current of 5.2 mA. It functions reliably across a temperature range of -40 °C to +85 °C.

Flip Flops Feature Summary

• Contains eight independent D-type flip-flops providing positive-edge triggering for data storage.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital logic storage applications
• Microprocessor system interface buffering

Flip Flops Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing status against the official datasheet. Confirm the SOIC-20 package dimensions match the design footprint requirements. Ensure the operating voltage range aligns with the target circuit's power supply specifications before finalizing procurement.

Flip Flops Selection Notes

Select this component when an octal storage solution with a dedicated clear function is required. The HC series offers standard CMOS performance suitable for general logic applications. Consider the 160 ns propagation delay and 2 V to 6 V operating range to ensure compatibility with the system timing and voltage levels.

Flip Flops Part Context

This part belongs to the SN74HC273 family of octal D-type flip-flops. It is designed for high-speed digital applications requiring parallel data latching. The device integrates eight edge-triggered D-type flip-flops into a single package, simplifying board layout for multi-bit data handling tasks.

Flip Flops Replacement Considerations

SN74HC273DW serves as a direct functional equivalent without the G4 suffix. SN74HCT273N provides compatible functionality with TTL-compatible input thresholds instead of CMOS inputs.

Flip Flops FAQ

What is the function of the clear input on the SN74HC273DWRG4?

The clear input asynchronously resets all eight flip-flops to a low state, regardless of the clock or data inputs.

How does the SN74HC273DWRG4 handle data updates?

Data is transferred from the D inputs to the Q outputs on the positive-going transition of the clock pulse.
