74ABT377CMSAX

Flip Flops Overview

The 74ABT377CMSAX is an octal D-type flip-flop manufactured by onsemi, housed in a 20-SSOP package. It features positive-edge triggering with a clock enable input for predictable state updates. The device operates within a 4.5 V to 5.5 V supply range and supports a maximum clock frequency of 200 MHz. Propagation delay is specified at 6.8 ns under 5 V and 50 pF load conditions. Output drive capabilities include 32 mA sourcing and 64 mA sinking currents. Static current consumption is limited to 50 µA, with an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with individual data inputs and non-inverting outputs
• Positive-edge triggered operation synchronized by a common clock signal
• High output drive capability supporting direct bus loading applications
• Glitch-free high impedance bus loading during power-up and power-down cycles

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Clock synchronization and timing control circuits
• Bus interface logic for high-speed data transfer
• Register files in microprocessor-based designs

Flip Flops Procurement Notes

Verify the specific suffix CMSAX against official onsemi documentation to confirm the 20-lead shrink small outline package (SSOP) configuration. Ensure compatibility with required voltage levels and thermal specifications for the intended application environment. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through manufacturer datasheets or material composition statements prior to procurement.

Flip Flops Selection Notes

Select this component when an octal register with high-speed performance and strong drive capability is required. The ABT series offers faster switching speeds compared to standard TTL alternatives. Consider the SSOP package constraints for PCB layout and thermal management. Evaluate the 6.8 ns propagation delay against system timing requirements. Verify that the 4.5 V to 5.5 V operating range aligns with the target power supply design.

Flip Flops Part Context

The 74ABT377CMSAX belongs to the 74ABT logic family, which provides advanced bipolar technology for high-speed operations. It is functionally similar to other octal D-type flip-flops like the 74ABT374 but includes a clock enable feature for enhanced control. The device is designed for applications requiring reliable data latching and high fan-out capabilities in complex digital circuits.

Flip Flops Replacement Considerations

Direct substitutes may include SN74ABT377ANSR from Texas Instruments. Verify pinout compatibility and electrical parameters before substitution. Alternative packages such as SOIC or TSSOP variants exist within the same logical family but require mechanical assessment.
