*1: VIN (max), IO1 (max) and IO2 (max) are restricted by the relation PD = (VIN – VO1) × IO1 + (VIN - VO2) × IO2.
*2: When mounted on glass-epoxy board of 30 × 30mm² (copper laminate area 4.3%)
Thermal protection may operate when the junction temperature exceeds 135°C.

*1: IS1 1 and IS1 2 are specified at the 5% drop points of output voltages VO1 and VO2 on the condition that VIN = the condition of protection starting current, IO = 10 mA.
*2: Output is OFF when the output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, the devices can be driven directly by LS-TTLs.
Channels 1 and 2 are turned on or off at the same time.
