M74HC377RM13TR

Flip Flops Overview

The M74HC377RM13TR is an octal D-type flip-flop manufactured by STMicroelectronics using silicon gate C2MOS technology. It features a positive-edge clock trigger controlled by a low enable input, transferring data from D to Q outputs. The device operates within a wide supply voltage range of 2V to 6V and supports a maximum frequency of 73 MHz at 5V. Key electrical parameters include a maximum static current of 4 µA, symmetrical output impedance with minimum drive currents of 4 mA for both high and low states, and propagation delays characterized as balanced tPLH and tPHL.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with synchronous positive-edge triggering
• Enable control mechanism allowing data transfer only when the input is low
• High noise immunity with defined minimum noise voltage thresholds relative to supply
• Robust protection circuits against static discharge and transient excess voltage on all inputs

Flip Flops Applications

• Parallel-to-serial data conversion in digital communication systems
• General-purpose register storage in microprocessor-based designs
• Shift register configurations for data sequencing applications

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeits. Confirm RoHS compliance status and specific manufacturing lot dates if required for long-term supply chain stability. Ensure proper handling procedures are followed during assembly to maintain ESD protection integrity. Cross-reference datasheet revisions to confirm pinout compatibility before integration into existing PCB layouts.

Flip Flops Selection Notes

Select this component for applications requiring high-speed octal storage with CMOS low power consumption. It offers performance comparable to LSTTL while maintaining true CMOS benefits. Consider the 73 MHz typical maximum frequency for timing constraints. Verify that the 2V to 6V operating range aligns with system voltage requirements. Ensure sufficient drive capability for connected loads given the 4 mA minimum output specification.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by STMicroelectronics. The M74HC377 variant specifically provides octal D-type flip-flop functionality. It is functionally compatible with the 54/74LS377 standard, facilitating design transitions between logic families. The RM13TR suffix indicates the specific tape and reel packaging format suitable for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

Direct substitutes include other manufacturers' octal D-type flip-flops such as the SN74HC377 from Texas Instruments or equivalent parts from Nexperia and onsemi. Verify pinout compatibility and electrical parameter alignment, particularly propagation delay and output drive strength, before substitution.
