CD74HC574M96

Overview

The CD74HC574M96 is a Texas Instruments octal D-type flip-flop with three-state outputs, manufactured in the HC logic series. It features single-ended inputs and outputs within a 20-pin SOIC surface-mount package. The device operates on a single supply voltage ranging from 2 V to 6 V. Key electrical specifications include a maximum propagation delay of 165 ns at 2 V under a 50 pF load, and a maximum power supply current of 8 uA. It supports an operating temperature range from -55 °C to +125 °C.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent storage elements per chip
• Three-state output capability allowing direct bus connection without external buffers
• Positive-edge triggering mechanism for reliable data capture on clock transitions
• Wide operating voltage range supporting low-power CMOS applications

Applications

Procurement Notes

Verify the specific suffix 'M96' against the manufacturer's official datasheet to confirm package dimensions and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the pinout diagram with your PCB footprint design to prevent installation errors. Confirm that the logic family voltage levels match your system's I/O standards before integration.

Selection Notes

Select this component when an octal register with high-impedance states is required for bus management. The HC series offers standard CMOS speed suitable for general digital logic. Consider the 20-pin SOIC package constraints for board space. Evaluate the 165 ns delay specification against your system's timing requirements to ensure signal integrity at the intended operating frequency.
