IR53H(D)420(-P2)
Recommended Operating Conditions
The input/output logic timing diagram is shown in figure 1. For proper operation, the device should be used
within the recommended conditions.
NOTE 2:
Care should be taken to avoid switching conditions where the V
S
node flies inductively below ground by more than 5V.
NOTE 3:
Enough current should be supplied to the V
CC
lead of the IC to keep the internal 15.6V zener diode clamping the
voltage at this lead.
