ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability.
Terminal Voltage (with respect to GND):
V_CC........................................................-0.3V to +6.0V
All Other Inputs (Note 1)..............-0.3V to (V_CC +3.0V)
Input Current:
V_CC.....................................................................20mA
GND...................................................................20mA
Output Current (all outputs)...............................20mA
ESD Rating...........................................................2kV
Continuous Power Dissipation
Plastic DIP
