DESCRIPTION
The 74LVC109A is a high-performance, low-voltage,
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families.
The 74LVC109A is a dual positive edge triggered
JK flip-flop featuring individual J and K inputs, clock (CP)
inputs, set (SD) and reset (RD) inputs and complementary
Q and Q outputs.
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 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 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.
