DM74AS74  
Dual D-Type Positive-Edge-Triggered Flip-Flop  
with Preset and Clear  
General Description  
The AS74 is a dual edge-triggered flip-flops. Each flip-flop  
has individual D, clock, clear and preset inputs, and also  
complementary Q and Q outputs.  
Features  
■ Switching specifications at 50 pF  
■ Switching specifications guaranteed over full tempera-  
ture and VCC range  
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.  
■ Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
■ Functionally and pin-for-pin compatible with Schottky  
and LS TTL counterpart  
■ Improved AC performance over S74 at approximately  
half the power  
Asynchronous preset and clear inputs will set or clear Q  
output respectively upon the application of LOW level sig-  
nal.
