CD74HCT574M

Overview

The CD74HCT574M is an octal D-type flip-flop manufactured by Harris Corporation, housed in a 20-pin SOIC package. It operates on a supply voltage range of 4.5V to 5.5V and features three-state outputs. The device supports a maximum operating frequency of 20 MHz with a load capacitance of 50 pF. It delivers a maximum output current of 6 mA and functions within a temperature range of -55°C to +125°C.

Feature Summary

Octal D-type flip-flop architecture with positive edge triggering
Three-state non-inverting outputs suitable for bus-oriented applications
CMOS construction providing low power consumption characteristics

Applications

Bus-oriented memory register storage
Industrial control system data latching
High-temperature electronic circuit design

Procurement Notes

Verify the manufacturer designation as Harris Corporation rather than Texas Instruments, as legacy documentation may vary. Confirm the specific suffix 'M' corresponds to the SOIC-20 package variant. Check RoHS compliance status, as older Harris production runs may not meet current environmental standards. Ensure the component meets the required -55°C to +125°C industrial temperature rating for your specific application environment.

Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for high-temperature environments. The HCT logic series ensures compatibility with standard TTL-driven systems while maintaining CMOS power efficiency. The wide operating voltage range of 4.5V to 5.5V provides flexibility in power supply design. Consider the 20-pin SOIC package for surface-mount assembly requirements.

Part Context

This part belongs to the 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. The CD74 prefix indicates it is a commercial-grade device from Harris Corporation's semiconductor division. As an octal flip-flop, it consolidates eight independent D-type registers into a single integrated circuit, simplifying board layout for multi-bit data handling applications.
