74HCT74DB,118

Overview

The 74HCT74DB,118 is a dual D-type flip-flop with positive-edge triggering from the HCT logic family. It operates on a single supply voltage ranging from 4.5V to 5.5V and features push-pull outputs. The device is housed in a 14-SO (SOIC-14) surface-mount package and supports an operating temperature range of -40°C to +125°C.

Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• Push-pull output configuration for robust signal driving
• Wide operating temperature range suitable for industrial environments

Applications

• Data storage and register applications
• Shift registers and serial-to-parallel conversion
• Timing and synchronization circuits

Procurement Notes

Verify the specific suffix '118' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the SOIC-14 footprint matches the target PCB design. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when dual independent D-flip-flops are required within a compact SOIC-14 package. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS power efficiency. Verify that the 4.5V to 5.5V supply range aligns with the system's power architecture.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices manufactured by Nexperia. The 74HCT74 specifically provides two independent D-type flip-flops, making it a fundamental building block for sequential logic circuits requiring data retention and edge-triggered state changes in digital systems.

Replacement Considerations

Cross-reference with other manufacturers' 74HCT74 equivalents in SOIC-14 packages. Verify pinout compatibility and electrical parameter alignment, particularly propagation delay and output drive strength, to ensure functional interchangeability without circuit modification.
