CD74HC574M96E4

Overview

The CD74HC574M96E4 is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and belongs to the HC logic series. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. It is housed in a 20-pin SOIC package. The component includes a clock input, eight data inputs, and eight corresponding outputs with enable control.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops on a single chip
• Three-state outputs allowing direct connection to bus systems
• Edge-triggered data storage triggered by the positive transition of the clock signal
• Wide operating temperature range suitable for industrial environments

Applications

• Registering digital data in microprocessor-based systems
• Bus-oriented memory applications requiring high-speed data latching
• Portable equipment utilizing low-voltage CMOS technology
• Industrial control systems requiring extended temperature stability

Procurement Notes

Verify the specific ordering suffix E4 indicates lead-free status and RoHS compliance when sourcing. Confirm the M96 variant matches the required package dimensions and marking specifications for your PCB layout. Ensure the supplier provides valid manufacturer documentation to guarantee authenticity. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Selection Notes

Select this component for designs requiring octal data storage with bus-compatible outputs. The HC series offers standard CMOS compatibility with TTL drive capabilities. Consider the propagation delay specifications relative to your system clock speed. Evaluate the thermal performance requirements against the specified operating temperature range for reliable long-term operation.

Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 574 designation specifically identifies it as an octal D-type flip-flop. The M96E4 suffix denotes the specific tape-and-reel packaging and environmental compliance attributes defined by the manufacturer for mass production distribution channels.

Replacement Considerations

Compatible substitutes include SN74HC574N for through-hole applications and CD74HC574M96 for similar surface-mount configurations. Verify that alternative parts maintain identical pinouts and electrical parameters to ensure circuit compatibility without redesign.
