description/ordering information

The ’ACT174 devices are positive-edge-triggered D-type flip-flops with a direct clear (CLR) input and are

Information at the data (D) inputs that meets the setup time requirements is transferred to the outputs on the

positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not

directly related to the transition time of the positive-going edge of CLK. When CLK is at either the high or low

level, the D input has no effect at the output.
