Product specification
Dual J-K positive edge triggered flip-flop with set and reset
74ALS109A
DESCRIPTION
The 74ALS109A is a dual positive edge-triggered JK-type flip-flop featuring individual J, K, clock, set, and reset inputs; also true and complementary outputs. Set (SD) and reset (RD) are asynchronous active-Low inputs and operate independently of the clock (CP) input. The J and K are edge-triggered inputs which control the state changes of the flip-flops as described in the function table. Clock triggering occurs at a voltage level and is not directly related to the transition time of the positive-going pulse. The J and K inputs must be stable just one setup time prior to the Low-to-High transition of the clock for predictable operation. The JK design allows operation as a D flip-flop by tying J and K inputs together. Although the clock input is level sensitive, the positive transition of the clock pulse between the 0.8V and 2.0V levels should be equal to or less than the clock to output delay time for reliable operation.

NOTES: 1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. 2. All typical values are at VCC = 5V, Tamb = 25C. 3. The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS. 4. Measure ICC with the clock input grounded and all outputs open, then with Q and Q outputs High in turn.
