CD74ACT174 (ACTIVE) Hex D-Type Flip-Flops with Reset

Hex D-Type Flip-Flops with Reset - CD74ACT174


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.
