54174 DM54174 DM74174 54175 DM54175 DM74175 Hex Quad D Flip-Flops with Clear June 1989 54174 DM54174 DM74174 54175 DM54175 DM74175 Hex Quad D Flip-Flops with Clear General Description These positive-edge triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic All 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 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 the high or low level the D input signal has no effect at the output Features Y Y Y Y Y Y Y Y 174 contains six flip-flops with single-rail outputs 175 contains four flip-flops with double-rail outputs Buffered clock and direct clear inputs Individual data input to each flip-flop Applications include Buffer storage registers Shift registers Pattern generators Typical clock frequency 40 MHz Typical power dissipation per flip-flop 38 mW Alternate Military Aerospace device (54174
