Each output is a switched, programmable constant current sink with a voltage compliance of 80 or 125 Volts. These circuits provide for simple interfaces with displays such as the Beckman, Burroughs Panaplex, Cherry or equivalents. Output Circuit Schematic (Each Section) Input Features: ü ü ü ü ü ü ü High Breakdown Voltage: 80V or 125V. High Input Voltage Capability: 40V TTL or MOS Compatible All Output Currents Programmed with Single Resistor Requires Few Additional Components Equivalent To DM-8889, MC3491, ITT-505 DC Restoring Input Diode GND Package Layout: Pin Connections DIONICS INC.
