NAND TYPE I POWER AMPLIFIER PAC, MODEL CC-045
GENERAL DESCRIPTION
The NAND Type I Power Amplifier PAC, Model CC-045 (Figure A-27), contains three
4-input and three 2-input NAND gates that can be used to drive heavy loads.
One of the 2-
input gates has a node connected to pin 7 which can be used for input expansion.
A three-
diode cluster is also provided 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 jumpeFed together on the connector into
which a CC-045 is inserted.
These jumpers should be made as short
as possible.
Pin 20 to pin 33
Pin 27 to pin 30
Pin 30 to pin 33
