HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is desirable to take
precautions appropriate to handling MOS devices. Advice can be found in Data Handbook IC24 under Handling MOS devices.
DC CHARACTERISTICS
VDD = 2.3 to 5.5 V; VSS = 0 V; Tamb = -40 to +85 °C; unless otherwise specified. TYP at 3.3 V and 25 °C.

NOTE:
1. Each I/O must be externally limited to a maximum of 25 mA and each octal (LED0-LED7 and LED8-LED15) must be limited to a maximum
current of 100 mA for a device total of 200 mA.
