Description

  These DM54175 positive-edge triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic. All DM54175 have a direct clear input, and the quad (175) version features complementary outputs from each flip-flop.
  Information at the D inputs meeting the setup and hold time requirements is transferred to the Q outputs on the positivegoing edge of the clock pulse. Clock triggering occurs at particular voltage level and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the high or low level, the D input signal has no effect at the output.
