1 / 7 page © 2000 Fairchild Semiconductor Corporation DS006109 www.fairchildsemi.com September 1986 Revised February 2000 DM74ALS74A Dual D Positive-Edge-Triggered Flip-Flop with Preset and Clear General Description The DM74ALS74A contains two independent positive edge-triggered flip-flops. Each flip-flop has individual D, clock, clear and preset 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 LOW level, the D input signal has no effect. Asynchronous preset and clear inputs will set or clear Q output respectively upon the application of low level signal. Features s Switching specifications at 50 pF s Switching specifications guaranteed over full tempera- ture and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin-for-pin compatible with Schottky and LS TTL counterpart s Improved AC performance over LS74 at approximately half the power Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Connection Diagram Function Table L = LOW State H = HIGH State X = Don't Care ↑ = Positive Edge Transition Q0 = Previous Condition of Q Note 1: This condition is nonstable; it will not persist when preset and clear inputs return to their inactive (HIGH) level. The output levels in this condi- tion are not guaranteed to meet the VOH specification.
