Strobed Hex Inverter/Buffer
High-Voltage Silicon-Gate CMOS
The IW4502B consists of six inverter/buffers with 3-state outputs.
A logic "1" on the OUTPUT ENABLE input produces a high
impedance state in all six outputs. This feature permits common busing
of the outputs, thus simplifying system design. A logic "1" on the
DIRECTION input switches all six outputs to logic "0" if the
OUTPUT ENABLE input is a logic "0".
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.
