361454 Direct Coupled - Inverter


The DCI Module contains two separate direct-coupled inverters. These inverters are designed to provide a fast, economical way of extending the fan-out of an AI or an AOI module by approximately a factor of 3. The lead between the AI or AOI output pin 9 and the DCI input pin 5 or 12 must be kept as short as possible for the full speed capability of this circuit to be realized. The collector resistor must be connected on the driving AI or AOI to provide the necessary base current drive to the DCI. The DCI collector resistor has been left programmable but must be connected on the card for the intended use of this module. Connect pin 2 to 3 and 8 to 9. The circuit will not drive long transmission lines of fast output transitions.
