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 µA at 18 V over full package-
temperature range; 100 nA at 18 V and 25°C
•

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 c ontains p rote ction ci rcuitr y to guard a gainst damage d ue to high st atic voltages or electr ic
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
