SN74LV273ADGSR

Flip Flops Overview

The SN74LV273ADGSR is an octal D-type flip-flop from the Texas Instruments LV logic series, housed in a VQFN-20 package. It operates within a supply voltage range of 2 V to 5.5 V and features non-inverting outputs with a maximum propagation delay of 10.5 ns at 5 V. The device includes a direct clear input for each trigger and supports typical output ground bounce below 0.8 V at 3.3 V. It provides eight independent data inputs and single-rail outputs, ensuring CMOS compatibility.

Flip Flops Feature Summary

• Octal configuration with eight independent D-type flip-flops
• Direct clear input functionality for immediate state reset
• Wide operating voltage range supporting 2 V to 5.5 V systems
• Low output ground bounce characteristics for signal integrity

Flip Flops Applications

• General-purpose digital data storage circuits
• Parallel-to-serial data conversion interfaces
• Microprocessor system address latching
• Industrial control logic state retention

Flip Flops Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the VQFN-20 package and reel packaging format required for your assembly process. Confirm that the LV series specifications meet your voltage and speed requirements, as this component differs from AHCT or LVTH variants. Ensure ESD handling protocols are followed during installation due to the sensitive CMOS input structure.

Flip Flops Selection Notes

Select this component when an octal latch with a global clear function is needed in a compact surface-mount footprint. The LV series offers lower power consumption compared to standard TTL equivalents. Consider the 10.5 ns propagation delay for timing constraints. Verify that the 2 V minimum supply voltage aligns with your system's power rails, as some applications may require higher voltage thresholds.

Flip Flops Part Context

This part belongs to the SN74LV273A family of octal D-type flip-flops. It is distinct from the SN74LV273AQ (automotive grade) and SN74LVTH273 (TTL-compatible input/output) variants. The DGSR suffix indicates a tape-and-reel packaging option suitable for automated surface-mount technology placement, differentiating it from tube-packaged versions like the DW or PWR.

Flip Flops Replacement Considerations

The SN74LV273ADWR is a pin-compatible alternative in a TSSOP-20 package. For automotive applications, consider the SN74LV273AQDGSRQ1. Standard TTL-compatible replacements include the SN74LVTH273 series, though input/output voltage levels differ significantly.
