MM74HC374WMX

Flip Flops Overview

The MM74HC374WMX is an octal D-type flip-flop manufactured by onsemi, belonging to the 74HC logic family. It features eight edge-triggered D flip-flops with three-state outputs in a single package. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 20-SOIC (0.295 inch, 7.50mm wide) package. Key electrical parameters include a maximum propagation delay of 40ns at 6V with 150pF load, a clock frequency of 35 MHz, and output drive currents of 7.8mA for both high and low states. Static current consumption is specified at 8 µA.

Flip Flops Feature Summary

• Octal configuration integrating eight independent D-type flip-flops into a single integrated circuit.
• Three-state outputs designed to facilitate direct connection to bus-organized systems without additional interface components.
• Non-inverting logic polarity ensuring true output signal transmission relative to input data.
• Edge-triggered operation synchronized with positive clock transitions for precise data latching.

Flip Flops Applications

• Implementation of buffer registers in digital signal processing circuits.
• Construction of I/O ports for microcontroller interfacing applications.
• Utilization as bidirectional bus drivers in system architecture designs.
• Deployment as working registers within complex logic control systems.

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels to ensure compliance with RoHS3 specifications. Confirm moisture sensitivity level classification, designated as MSL 3, to adhere to proper storage and handling protocols during assembly. Validate that the specific SOIC-20 package dimensions align with target PCB footprint requirements. Ensure operational temperature ranges meet the intended environmental conditions for reliable performance.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple parallel data storage elements with bus-compatible output capabilities. The wide supply voltage range supports compatibility with various logic levels across different circuit sections. Consider the propagation delay characteristics for timing analysis in high-speed digital applications. Evaluate the surface-mount packaging format against available assembly equipment and board space constraints.
