SN74HCT74DE4

Flip Flops Overview

The SN74HCT74DE4 is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features two independent flip-flops with preset (PRE) and clear (CLR) inputs within a 14-pin SOIC package. The device operates with a maximum clock frequency of 46MHz and exhibits a maximum propagation delay of 25ns at 5.5V with a 50pF load. It is designed for high-speed digital applications requiring reliable data storage and transfer capabilities.

Flip Flops Procurement Notes

Verify the component authenticity by checking the manufacturer's marking on the package against official datasheet specifications. Ensure the ordering suffix matches the required package type and environmental compliance standards. Cross-reference the part number with the latest Texas Instruments documentation to confirm current production status and availability before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when dual independent D-type flip-flops are required in a compact surface-mount package. Consider the 46MHz clock speed and 25ns propagation delay for timing-critical designs. Ensure the operating voltage range aligns with the system's power supply requirements. Verify that the 14-pin SOIC footprint fits the available PCB space constraints.

Flip Flops Part Context

This device belongs to the HCT logic family, which offers CMOS performance with TTL-compatible inputs. The '74' series designation indicates standard commercial temperature range operation. The DE4 suffix specifies the 14-lead small-outline integrated circuit package with lead-free composition and RoHS compliance, suitable for automated assembly processes.

Flip Flops Replacement Considerations

Compatible substitutes include other dual D-type flip-flops from the same HCT family, such as the SN74HCT74N or SN74HCT74PW, provided pin compatibility and electrical characteristics match the original design requirements.
