SN74F574DW

Flip Flops Overview

The SN74F574DW is an octal edge-triggered D-type flip-flop from the Texas Instruments 74F series, housed in a 20-pin SOIC package. It features non-inverting outputs with three-state capability and TTL inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8.5 ns at 5 V with 50 pF load, a maximum clock frequency of 100 MHz, and output drive currents of -3 mA (high) and 24 mA (low). It functions across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs allow direct connection to bus lines for efficient data transmission management.
• Edge-triggered operation ensures data capture occurs precisely on the positive transition of the clock signal.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in digital systems
• Bus interface buffering applications

Flip Flops Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit products. Confirm that the ordering information matches the exact logic family and pinout requirements of your design.

Flip Flops Selection Notes

Select this component when high-speed performance is required in standard 5 V logic environments. The 74F series offers faster switching speeds compared to HC or HCT families. Consider the three-state output feature if bus sharing is necessary. Verify that the input voltage levels are compatible with TTL standards used in the system.

Flip Flops Part Context

This part belongs to the SN74F574 family of octal D-type flip-flops. It shares functional characteristics with other variants like the SN74F574DWR, differing primarily in packaging and shipping format. The 74F series represents a high-speed variant within the broader 74xx logic ecosystem, designed for applications demanding rapid processing times.
