Driving a low-impedance line
As was described in section 3.15 above, the sink current of the IC itself is only 3.6 mA (TYP.), which is
inadequate for driving a low-impedance line such as a video line. As is shown in Figure 10, it is possible to
drive a low-impedance line if a bypass resistor rated between 150 and 600
:
is connected and a capacitor
coupling is used to link the increased drive capacity of the output-level emitter-follower.
In this case, the output current (I
O
= (V
O(CM)
/ R
L
) generated based on the R
L
value should not be more than 20
mA.
