description/ordering information
The ’ACT174 devices are positive-edge-triggered D-type flip-flops with a direct clear (CLR) input and are
designed for 4.5-V to 5.5-V VCC operation.
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.
