Flip Flops Procurement Notes

Verify the specific suffix 'NG' against official onsemi documentation to confirm package type and availability status. Ensure compatibility with required operating temperature ranges and supply voltage specifications before integration. Cross-reference with current datasheets to confirm RoHS compliance and material composition declarations. Check for any obsolescence notices or recommended replacement parts if the component is discontinued.

Flip Flops Selection Notes

Select this component when designing systems requiring octal D-type storage with high-speed performance and strong drive capabilities. The 74ACT series offers faster switching speeds compared to standard HC or HCT families while maintaining TTL input compatibility. Consider the 200 MHz maximum clock frequency and 11 ns propagation delay for timing-critical applications. Ensure the 4.5V to 5.5V supply voltage range aligns with the system power architecture.

Flip Flops Part Context

The MC74ACT273 is part of onsemi's 74ACT logic family, which combines the speed of AC logic with the input compatibility of TTL logic. This octal D-flip-flop serves as a fundamental building block for sequential logic circuits. It is often used in conjunction with other 74ACT devices such as latches and tri-state buffers to create complex digital systems. The device is designed for surface-mount applications using SOIC packaging.
