POWER AMPLIFIER PAC, MODEL PA-335
The Power Amplifier PAC, Model PA-335 (Figures A-98 and A-99),
contains
six 3-input NAND gates that can be used for driving heavy loads.
Each gate has two elec-
trically common outputs to reduce load distribution current on any single wire.
Built-in
short-circuit protection limits output current if the output is accidentally grounded.
Each gate performs the NAND function for positive logic (positive voltage is a ONE
and Ov is a ZERO).
For negative logic, it becomes a NOR gate.
When all inputs to a gate
are at positive or not connected, the output goes to ground.
When any input is at ground,
the output goes to a positive voltage.
