Flip Flops Procurement Notes

Verify the specific suffix 'ADTG' against the manufacturer's latest datasheet to confirm the package type and tape/reel specifications. Ensure that the procurement source provides valid RoHS compliance documentation as required for modern electronic assemblies. Cross-reference the part number with official obsolescence notices to confirm availability status before finalizing orders.

Flip Flops Selection Notes

Select this component when an octal register with a global reset function is required in designs operating between 2V and 6V. The HC series offers balanced speed and power consumption suitable for general-purpose logic applications. Consider the DIP-20 package for through-hole prototyping or legacy board compatibility where surface-mount alternatives are not feasible.

Flip Flops Part Context

Flip Flops FAQ

Is the reset input synchronous or asynchronous?

The reset input is asynchronous and active-low, meaning it overrides the clock signal to clear all outputs immediately.

What is the maximum operating voltage for this device?

The maximum operating supply voltage is 6.0 V, with a minimum of 2.0 V.
