SN74HCS273DGSR

Flip Flops Overview

The SN74HCS273DGSR is an octal D-type flip-flop from Texas Instruments' HCS series, housed in a 20-TFSOP package. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 135 MHz. The device features Schmitt-trigger inputs for noise immunity and provides push-pull outputs with a propagation delay of 29.1 ns. It functions over an extended temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Incorporates Schmitt-trigger inputs to enhance noise rejection and signal integrity.
• Provides wide operating voltage flexibility ranging from 2 V to 6 V.
• Features push-pull output drivers for robust digital logic interfacing.

Flip Flops Applications

• General-purpose digital data storage systems
• Industrial control logic circuits
• Automotive electronic modules

Flip Flops Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the TSSOP-20 or similar thin-shrink package variant as listed in official TI documentation. Confirm RoHS compliance status and ensure the ordering part number matches the exact package width and lead finish specifications required for your PCB assembly process.

Flip Flops Selection Notes

Select this component when wide voltage operation between 2 V and 6 V is required, unlike standard 5 V-only logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments where clean switching thresholds are critical. Ensure the 29.1 ns propagation delay meets the timing constraints of your target application speed.

Flip Flops Part Context

This device belongs to the SNx4HCS273 family of octal D-type flip-flops. It shares functional similarities with the SN74HCT273 but offers broader voltage tolerance and Schmitt-trigger inputs. The DGSR suffix indicates a specific tape-and-reel packaging format optimized for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

SN74HCS273DR: Same logic function and electrical characteristics in a SOIC-20 package instead of TFSOP. SN74HCS273PW: Identical performance specifications housed in a TSSOP-20 package. Verify pin compatibility and thermal requirements before substituting these alternative packages.
