SN74LS74AN Electronic IC Chips DUAL D-TYPE POSITIVE-EDGE-TRIGGERED FLIP-FLOPS
SN74LS74A
DUAL D-TYPE POSITIVE-EDGE-TRIGGERED FLIP-FLOPS
LOW POWER SCHOTTKY
The SN74LS74A dual edge-triggered flip-flop utilizes Schottky TTL circuitry to produce high speed D-type flip-flops. Each flip-flop has individual clear and set inputs, and also complementary Q and Q outputs.
Information at input D is transferred to the Q output on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the HIGH or the LOW level, the D input signal has no effect.
