Supply Voltage (VCC) DC................................................................ -0.3V to 5.5V
Supply Voltage (VCC) Transient ........................................................ -0.3V to 6V
Driver Supply Voltage (VC1, VCCL, LDVCC) DC.................................. -0.3V to 16V
Driver Supply Voltage (VC1, VCCL, LDVCC) Transient ........................ -0.3V to 18V
Input Voltage (SS/DIS)..................................................................... -0.3V to 5.5V
Output Drive Peak Current Source (HO, LO) ...................................... 1A (500ns)
Output Drive Peak Current Sink (HO, LO) .......................................... 1A (500ns)
Operating Junction Temperature ..................................................................150
°C
Storage Temperature Range .......................................................... -65
°C to 150°C
Lead Temperature (Soldering 180 seconds) .................................................235
°C
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal
.
The limitation on transient time is thermal and is due to zener diodes on the
supply pins, brief application of maximum voltages will increase current into that
pin and increase package power dissipation..

The
θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow.
