Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Shift register implementations
• Timing and control logic systems

Flip Flops Procurement Notes

Verify the specific suffix DWR2G corresponds to the SOIC-20 package and tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Cross-reference the manufacturer part number with official onsemi documentation to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with high-speed performance and wide voltage tolerance is required. The 74AC series offers faster switching than standard 74HC devices while maintaining CMOS input characteristics. Consider the ±24 mA output drive if driving moderate capacitive loads directly. Verify that the 20-SOIC footprint fits your PCB layout constraints and that the 2 V to 6 V supply range aligns with your system power rails.
