Dual 4-Stage Static Shift Register
High-Voltage Silicon-Gate CMOS
The IW4015B consists of two identical, independent, 4-stage
serial-input/parallel-output registers. Each register has independent
CLOCK and RESET inputs as well as a single serial DATA input. "Q"
outputs are available from each of the four stages on both registers. All
register stages are D-type, master-slave flip-flops. The logic level
present at the DATA input is transferred into the first register stage and
shifted over one stage at each positive-going clock transition. Resetting
of all stages is accomplished by a high level on the reset line. Register
expansion to 8 stages using one IW4015B package, or to more than 8
stages using additional IW4015B's is possible.
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1
A at 18 V over full package-
temperature range; 100 nA at 18 V and 25
C
Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

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.
