Maximum Output Current Load Test Conditions

The output load resistor values (R1 to R8) are set so that when an ‘‘on’’ level signal is input to inputs 1 and 2, a current of 15 to

30 mA max. flows to the sink side and the source side (approximately 2 mA on the V1 source side).

STR Pin Usage

Input 1

Input 2

VCC –VEE =35 V

RX =8 R

C1to4=10 µF

C5=33 µF

R:1 W or more

TR1 to 4: 2SA984

E or F rank

TR5 to 9: 2SC2274

E or F rank

Input 1

Input 2

Start-up

circuit

The STR input is configured as shown left.

.

The STR is either shorted with VCC or connected

to VCC via an external resistor.

.

It is possible to use a separate power supply

(VIN) such that 2 V < VIN <VCC for current

saving.

(2 V or more required for STR)

(2 V<VIN <VCC)
