Applications Information
with biphase outputs Because the collector of output tran-
sistor Q12 is the only internal connection to V
termination to the power supply voltage allows one to obtain
inverted video at pin 10 Black level on the non-inverted
video output (pin 8) is set to 1 5V by the voltage divider on
pin 6
designed using multiple LM1201 devices All outputs can

be OR’ed together assuming no more than one channel is
selected at any given time Channel selection is accom-
plished by keeping the appropriate SELECT SWITCH open
Closing the SELECT SWITCH on a given channel disables
that channel’s output (pin 8) leaving it in a high impedance
state A single pair of contrast and brightness potentiome-
ters control the selected channel’s gain and output DC
