CS44600
1. CHARACTERISTICS AND SPECIFICATIONS
(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical
performance characteristics and specifications are derived from measurements taken at nominal supply voltages
and T_A = 25°C.)

WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
is not guaranteed at these extremes.
2. Any pin except supplies. Transient currents of up to ±100 mA on the input pins will not cause SCR latch-up.
3. The maximum over/under voltage is limited by the input current.
