SN74ALS273DWRG4

Flip Flops Overview

The SN74ALS273DWRG4 is an octal D-type flip-flop from the Texas Instruments ALS logic series, housed in a 20-pin SOIC package. It features positive-edge triggering and includes a master clear input. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 15 ns at 5 V with 50 pF load, a maximum clock frequency of 35 MHz, and static current consumption of 20 mA. Output drive capabilities are specified as -2.6 mA for high level and 24 mA for low level. It supports surface mount installation and functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements in a single integrated circuit
• Positive-edge triggering mechanism synchronized by a single clock input line
• Master clear functionality allowing asynchronous reset of all flip-flops
• TTL-compatible inputs and outputs ensuring interface compatibility with standard logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Data buffering and temporary storage applications
• Timing control logic for sequential operations

Flip Flops Procurement Notes

Verify the specific ordering suffix G4 confirms RoHS compliance status against the latest manufacturer documentation. Confirm the SOIC-20 package dimensions match PCB footprint requirements. Ensure supply voltage levels remain within the 4.5 V to 5.5 V operational range to maintain signal integrity and prevent device damage during operation.

Flip Flops Selection Notes

Select this component when high-speed switching is required compared to standard LS logic, while maintaining TTL compatibility. The ALS series offers improved speed-power product characteristics. Consider the 20-pin SOIC package for surface mount assembly constraints. Evaluate power dissipation limits given the 20 mA static current draw relative to system thermal management capabilities.

Flip Flops Part Context

This part belongs to the SN74ALS273 family of octal D-type flip-flops. The G4 suffix typically indicates Green/RoHS-compliant manufacturing. It serves as a higher-speed alternative to the SN74LS273 series while retaining similar pinout and logical functionality. The device is designed for general-purpose digital logic applications requiring parallel data storage.

Flip Flops Replacement Considerations

SN74ALS273DW is the non-RoHS equivalent. SN74HC273DWRG4 offers CMOS technology with lower power but slower speed (160 ns). SN74AHC273DWR provides faster performance (7.4 ns) with CMOS inputs. Verify voltage compatibility and package dimensions before substitution.
