DM74ALS174 DM74ALS175 Hex/Quad D-Type Flip-Flops with Clear September 1986 Revised February 2000 DM74ALS174 DM74ALS175 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. Both have an asynchronous clear input, and the quad (DM74ALS175) version features 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 Advanced oxide-isolated ion-implanted Schottky TTL process s Pin and functional compatible with LS family counterpart s Typical clock frequency maximum is 80 MHz s Switching performance guarant...
