74ABT377CSJX

Flip Flops Overview

The onsemi 74ABT377CSJX is an octal D-type flip-flop belonging to the ABT logic series, housed in a 20-SOP package. It features eight non-inverting outputs with high sink capability of 64 mA and source capability of 32 mA. The device operates within a supply voltage range of 4.5 V to 5.5 V, supporting clock frequencies up to 200 MHz. Propagation delay is specified at 6.8 ns under standard load conditions. It includes a clock enable function for predictable state transitions and ensures glitch-free bus loading during power cycles.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with individual data inputs and Q outputs
• High output drive capability with 64 mA sink and 32 mA source current
• Clock enable functionality for controlled state updates on positive edge
• Glitch-free bus loading maintained throughout entire power-up and power-down cycle

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital data buses
• Register file storage elements in high-speed logic systems
• Timing synchronization and signal registration

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as this part may be discontinued. Ensure proper ESD handling procedures are followed during storage and installation. Validate package markings against datasheet specifications to prevent counterfeit substitution.

Flip Flops Selection Notes

Select this component for applications requiring high-speed octal data storage with strong drive capabilities. Consider the 20-SOP package constraints for PCB layout. Evaluate thermal performance within the -40°C to +85°C operating range. Compare propagation delay requirements against system timing budgets. Assess power consumption levels relative to other ABT series alternatives.

Flip Flops Part Context

This device belongs to the 74ABT family of high-speed CMOS logic products. It serves as a registered version of the 74ABT373 transparent latch, providing edge-triggered operation instead of level-sensitive transparency. The ABT series combines BiCMOS technology benefits with standard logic compatibility, offering superior speed and drive strength compared to earlier generations.
