74ABT377CSC

Flip Flops Overview

The onsemi 74ABT377CSC is an octal D-type flip-flop featuring a clock enable function, housed in a 20-lead SOIC package. It operates within a voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 200 MHz. The device exhibits a typical propagation delay of 6.8 ns at 5 V with 50 pF load. Output drive capabilities include 32 mA source and 64 mA sink currents. Static supply current is limited to 50 µA, and input capacitance is 5 pF. It functions reliably across an operating temperature range of -40°C to 85°C.

• Guaranteed latchup protection exceeding 100 mA

Flip Flops Applications

• High-speed parallel data storage systems
• Buffered register applications in communication equipment
• Control logic for high-performance computing architectures
• Data acquisition systems requiring edge-triggered sampling

Flip Flops Procurement Notes

Verify the specific ordering suffix 'CSC' corresponds to the 20-lead Small Outline Integrated Circuit (SOIC) package variant. Confirm that the component meets the required JEDEC MS-013 standard dimensions. Ensure the procurement channel provides valid traceability documentation for the onsemi manufacturer origin. Cross-reference the date code against current production status to avoid obsolete stock issues.

Flip Flops Selection Notes

Select this component when an octal D-type register with clock enable is required for 5V logic interfaces. The ABT technology offers superior speed compared to standard AC/ACT families while maintaining compatible pinouts. Consider the 64 mA sink capability for direct driving of heavy loads without external buffers. Evaluate the 200 MHz clock limit against system timing requirements to ensure signal integrity.

Flip Flops Part Context

This part belongs to the 74ABT series of high-speed CMOS logic devices manufactured by onsemi. The series utilizes advanced bipolar-CMOS technology to achieve performance levels between standard TTL and pure CMOS solutions. The 74ABT377 specifically addresses the need for high-density octal registers in complex digital systems requiring fast switching speeds and robust noise immunity.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include the MC74ABT377CSC from onsemi or equivalent variants from other manufacturers adhering to the same JEDEC outline. Verify that replacement parts maintain the identical 20-SOIC footprint and electrical specifications. Ensure the alternative source guarantees the same latchup protection levels and output drive currents.
