IDT74LVC109A
DESCRIPTION:
The LVC109A dual J-K flip-flop with set and reset, positive-edge trigger
is built using advanced dual metal CMOS technology. This device features
individual J, K inputs, clock (CP) inputs, set (SD) and reset (RD) inputs; also
complementary Q and Qoutputs.Thesetandresetareasynchronousactive
low inputs and operate independently of the clock input. The J and K inputs
control the state changes of the flip-flops as described in the function table.
TheJandKinputsmustbestableonesetuptimepriortothelow-to-highclock
transition for predictable operation. The J-K design allows operation as a
D-type flip-flop by tying the J and K inputs together.
Inputs can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.
The LVC109A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
