DM74LS174 • DM74LS175 Hex/Quad D-Type Flip-Flops with Clear August 1992 Revised April 2000 DM74LS174 • DM74LS175 Hex/Quad D-Type 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) 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 the HIGH or LOW level, the D input signal has no effect at the output. Features s DM74LS174 contains [ ... ]
