* 1: For normal use, connect VCC2 and VC.

For applications whose thermal conditions are more demanding, TOSHIBA recommends an external resistor

(REXT : approx. 0.9 Ω / 2W) be connected between VCC2 and VC.

* 2: When connecting an external resistor between BVCC2 and VC, to avoid parasitic sub currents, set the

voltage between VC and OUT as 0.3 V or more.

Set the external resistor value so that the voltage between VC and OUT is 0.3 V or more at the maximum

temperature of the operating temperature range.

INPUT CIRCUIT : IN, ENABLE

Note:

Since the states of the input pins (pins 3 to 10)

are the same as those at high-level input, set

the pins for unused channels to GND.

Output voltage (Temperature characteristic)

Output Voltage (VOH) has a Temperature Characteristic of 5.8 mV / °C, care must be taken to keep

Junction Temp (Tj) within safety Limits.
