is reached, TS7318
switches through.

Signal path:
The circuit shown in Fig. 3 corresponds in principle with the circuit in the manual, but components which are not
|
absolutely essential to its basic understanding have been omitted.
The transistors 7310 and 7316 are to be
considered as switches rather than am-
sce'
plifier elements.
The power supply is
switched on and off via the +STBY and
-STBY voltages respectively.
