Overview
INTEGRATED CIRCUITS 74ALS109A Dual J-K positive edge-triggered flip-flop with set and reset Product specification IC05 Data Handbook 1991 Feb 08 Philips Semiconductors Philips Semiconductors 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 b...
