M74HC73TTR

Flip Flops Overview

The M74HC73TTR is a high-speed CMOS dual D-type flip-flop with preset and clear, manufactured using silicon gate C2MOS technology. It features two independent D-type flip-flops, each with a data input (D), clock input (CP), preset (PRE), clear (CLR), and complementary outputs (Q and Q-bar). The device operates within a wide voltage range of 2 V to 6 V, ensuring compatibility with various logic families. It offers symmetrical output impedance and balanced propagation delays, making it suitable for applications requiring precise timing control. The component includes protection circuits against static discharge and transient excess voltage on all inputs.

Flip Flops Procurement Notes

Verify the exact ordering code matches M74HC73TTR, noting that 'TT' indicates tape-and-reel packaging. Confirm the manufacturer is STMicroelectronics or authorized licensee, as this part may be produced under license. Check for RoHS compliance and ECOPACK2 package specifications if environmental regulations apply. Ensure the datasheet version corresponds to the latest revision for accurate electrical characteristics. Validate that the supplier provides traceability documentation for quality assurance purposes.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with preset and clear is required in a design. Consider the 2 V to 6 V operating range for compatibility with system voltage levels. Evaluate the 15 ns typical propagation delay for timing constraints in digital circuits. Verify that the SOIC-14 or similar package fits the PCB layout requirements. Compare power dissipation characteristics if low-power operation is critical for the application environment.
