MC74HCT374ADWR2G

Flip Flops Overview

The MC74HCT374ADWR2G is an octal D-type flip-flop from the 74HCT logic family, manufactured by onsemi. It features eight non-inverting outputs with three-state control, housed in a 20-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 30 MHz. Key electrical characteristics include a propagation delay of 31 ns at 5 V with 50 pF load, and output drive currents of 6 mA for both high and low states. It functions across an extended temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering

• Non-inverting data path with single-ended input/output configuration

Flip Flops Applications

• Bus-oriented memory register implementations
• 8-bit shift registers for data serialization
• Parallel-to-serial conversion circuits
• High-speed buffering applications requiring three-state isolation

Flip Flops Procurement Notes

Verify that the ordering suffix 'DWR2G' corresponds to the SOIC-20 package and tape-and-reel packaging format. Confirm RoHS compliance status as indicated in official documentation. Ensure moisture sensitivity level (MSL) handling procedures are followed during storage and assembly. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times prior to procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring octal latching with three-state output capability under 5 V logic levels. The HCT series ensures compatibility with TTL-driven interfaces while maintaining CMOS power efficiency. Consider the 31 ns propagation delay and 30 MHz clock limit for timing-critical designs. The wide operating temperature range makes it suitable for industrial environments where thermal stability is required alongside standard logic interface requirements.

Flip Flops Part Context

This part belongs to the MC74HCT374A series of octal D-type flip-flops produced by onsemi. It is part of the broader 74HCT logic family, which bridges CMOS technology with TTL input specifications. The device serves as a fundamental building block for sequential logic circuits, providing reliable data storage and transfer functions in digital systems requiring parallel data handling with controlled output impedance.

Flip Flops Replacement Considerations

Publicly confirmed substitute part numbers include MM74HCT374WM and CD74HCT374M96. These alternatives offer similar functional characteristics within the 74HCT octal D-type flip-flop category. Verify pinout compatibility and package dimensions before substitution to ensure seamless integration into existing PCB layouts without requiring design modifications.
