High-Performance Silicon-Gate CMOS
The IN74HCT109 is identical in pinout to the LS/ALS109. The
IN74HCT109 may be used as a level converter for interfacing
TTL or NMOS outputs to High Speed CMOS inputs.
This device consists of two J-
K
flip-flops with individual set,
reset, and clock inputs. Changes at the inputs are reflected at the
outputs with the next low-to-high transition of the clock. Both Q to
Q
outputs are available from each flip-flop.

Both outputs will remain high as long as
Set and Reset are low., but the output
states are unpredictable if Set and Reset
go high simultaneously.

This device contains protection circuitry to guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of any voltage
higher than maximum rated voltages to this high-impedance circuit. For proper operation, V
IN
and
V
OUT
should be constrained to the range GND≤(V
IN
or V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or
V
CC
). Unused outputs must be left open.
