Note
1. The supply voltages VCCA, VCCD and VCCO may have any value between −0.3 and +7.0 V provided that the supply
voltage differences ∆VCC are respected.
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
