DM74S174 DM74S175 Hex/Quad D Flip-Flop with Clear
General Description
These positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop lo gic. All h ave a d irect cle ar input, and the quad (DM74S175) versions feature complementary outputs from each flip-flop. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input is at either th e H IGH or LOW l evel, th e D i nput si gnal has no effect at the output.
