• The sourcing current of the pin is indicated with “+”.

• The range that a control voltage is held in low level :

Pin 33, pin 35, pin 37, pin 31, pin 32, pin 36, pin 49, pin 50 : 0 V

∼ 0.8 V

Pin 8

: 0 V ∼ 0.5 V

• The range that a control voltage is held in high level :

Pin 33, pin 35, pin 37, pin 31, pin 32, pin 36, pin 49, pin 50 : 2.0 V

∼ 5.5 V

Pin 8

: 2.5 V ∼ 5.5 V

• Pin 31, pin 32,pin 36,pin 49 and pin 50 builds in an input voltage limitation circuit.

• In the case beyond the voltage of the input voltage limitation circuit, leakage current depends on inside resistance.

• When resistance is connected to a pin, current decreases by the sum total of resistance and internal resistance.

Note) The characteristics listed above are reference values based on the IC design and are not guaranteed.
