MC74HC574AFELG

Flip Flops Overview

The MC74HC574AFELG is an octal D-type flip-flop manufactured by onsemi, featuring three-state non-inverting outputs. It operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 35 MHz. The device utilizes positive edge triggering to latch data from its inputs. It is housed in a 20-SOIC package with a width of 5.30mm. The component exhibits a maximum propagation delay of 27ns at 6V with a 50pF load and draws a static current of 4 µA. It is designed for surface mount installation and functions reliably across a temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit
• Three-state output capability allowing high-impedance states for bus-oriented applications
• Positive edge-triggered operation synchronizing data transfer with the rising clock edge
• CMOS technology ensuring low input current and compatibility with standard logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in digital systems
• Memory buffering and latching operations
• General-purpose digital storage applications

Flip Flops Procurement Notes

Verify the specific suffix 'FELG' against official manufacturer documentation to confirm exact packaging and compliance status. Confirm RoHS compliance details as historical records indicate potential variations. Ensure the procurement source provides valid traceability for this discontinued or obsolete part number before finalizing orders.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for high-temperature environments up to 125°C. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the 35 MHz clock speed limit against system timing requirements. Verify that the 2V to 6V operating voltage range aligns with the target power supply design.
