General description
The 74HC109; 74HCT109 is a dual positive edge triggered JK flip-flop featuring
individual nJ and nK inputs. It has clock (nCP) inputs, set (nSD) and reset
(nRD) inputs and complementary nQ and nQ outputs. The set and reset are
asynchronous active LOW inputs and operate independently of the clock input.
The nJ and nK inputs control the state changes of the flip-flops as described
in the mode select function table. The nJ and nK inputs must 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 connecting
the nJ and nK inputs together. Inputs include clamp diodes. It enables the use
of current limiting resistors to interface inputs to voltages in excess of
VCC.
Schmitt-trigger action in the clock input makes the circuit highly tolerant to
slower clock rise and fall times.
