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 V to 5.5 V; VSS = 0 V; Tamb = –40 °C to +85 °C; unless otherwise specified.

NOTES:

1. VDD must be lowered to 0.2 V in order to reset part.

2. Each I/O must be externally limited to a maximum of 25 mA and the device must be limited to a maximum current of 100 mA.

3. The total current sourced by all I/Os must be limited to 85 mA.
