74ABT374CSJX

Flip Flops Overview

The onsemi 74ABT374CSJX is an octal D-type flip-flop belonging to the ABT logic series, designed for high-speed digital applications. It features a single element with eight bits per element, operating within a supply voltage range of 4.5V to 5.5V. The device utilizes positive-edge triggering and provides non-inverting outputs with three-state capability. Key electrical parameters include a maximum propagation delay of 5ns at 5V with 50pF load, a clock frequency of 200 MHz, and output drive currents of 32mA (high) and 64mA (low). Static current consumption is specified at 50 µA, with an input capacitance of 5 pF. It operates across a temperature range of -40°C to 85°C and is housed in a 20-SOP package.

Flip Flops Feature Summary

• High-speed performance with 200 MHz clock frequency and 5ns propagation delay
• Strong output drive capability with 64mA sink and 32mA source currents
• Three-state non-inverting outputs for bus-oriented systems
• Positive-edge triggered operation for predictable data capture

Flip Flops Applications

• Parallel data storage and buffering in high-speed digital circuits
• Bus-oriented memory register implementations
• Clock domain crossing synchronization
• Data acquisition system interfaces

Flip Flops Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Procurement must rely on existing stock from authorized distributors or secondary market suppliers. Verify lot dates and physical condition carefully, as availability is limited. Cross-reference with active replacement parts from the same manufacturer family if long-term supply stability is required for production environments.

Flip Flops Selection Notes

Select this part only when specific legacy compatibility with the ABT series is mandatory. Consider the 20-SOP package dimensions and pinout for PCB layout constraints. Evaluate the 5.5V maximum supply limit against system power rails. Compare performance metrics like propagation delay and drive strength against newer alternatives if design flexibility allows, ensuring interface requirements match the non-inverting three-state output configuration.

Flip Flops Part Context

The 74ABT374CSJX is part of the broader 74ABT374 family produced by onsemi. It shares functional characteristics with other variants such as the 74ABT374CMTCX and 74ABT374CSC, differing primarily in packaging style and suffix codes. These devices are engineered for applications requiring fast switching speeds and robust noise immunity typical of advanced BJT-based logic families, serving as critical components in complex digital signal processing architectures.
