DESCRIPTION

The 74LV109 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT109.

The 74LV109 is a dual positive-edge triggered JK featuring individual J, K

) inputs; also complementary Q and Q outputs.

inputs, clock (CP) inputs, set (SD) and reset

The set and reset are asynchronous active 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 mode select function table. The J and K be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.

The JK

design allows operation as a D-type flip-flop by tying the

J and K

inputs together.

Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability .
