NAND TYPE II POWER AMPLIFIER PAC, MODEL CC-073
GENERAL DESCRIPTION
The NAND Type II Power Amplifier PAC, Model CC-073 (Figure A-31), contains six
3-input NAND gates that can be used to drive heavy loads.
One of the gates has a node con-
nected to pin 8 which can be used for input expansion.
A three -diode cluster is also pro-
vided for expansion of input gating.
Built-in short circuit protection limits the output current
if the output is accidentally grounded.
CIRCUIT FUNCTION
Each gate performs the NAND function for positive logic and the NOR function for
negative logic.
When all inputs to a gate are positive or not connected, the output will be at
ground.
If
any input is at ground, the output goes to a positive voltage.
NOTE
The following pins must be jumpered together on
the connector into which a CC-073 is inserted.
These jumpers should be made as short as possible.
