Notes:
1. Voltage values, except interemitter voltage,
are witl:! respect to network ground terminal.
2. This is the voltage between two emitters of
a mUltiple-emitter transistor.
3. This is the maximum voltage which should
be applied to any output when it is in the
off state.
POSITIVE LOGIC: r= A 6
