Notes:
1. H = High Voltage Level, L = Low Voltage Level,
HI-Z = High Impedance, X = Don’t Care
2. A pull-up resistor should be provided for power-up protection.
Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Storage Temperature .................................................................. –65°C to +150°C
Ambient Temperature with Power Applied ................................. –40°C to +85°C
Supply Voltage to Ground Potential (Inputs & V
CC
Only)........... –0.5V to +7.0V
Supply Voltage to Ground Potential (Outputs & D/O Only) ........ –0.5V to +7.0V
DC Input Voltage .......................................................................... –0.5V to +7.0V
DC Output Current......................................................................................120mA
Power Dissipation ..........................................................................................0.5W
Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above those
indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect
reliability.
