The data conversion (inversion) is determined by the selection of data latches which control the output driver transistors. Applications A positive true output option causes a VMEbus logical one to turn the corresponding output transistor ON, which supplies the Relay drivers user with zero volts. Triac drivers Lamp drivers The negative true output option causes a VMEbus logical one to LED drivers turn the corresponding output transistor OFF, which supplies the Solenoid drivers user with an open circuit for open-collector output circuits or High current, high voltage drivers with a high for electronic switch type output circuits. Hammer drivers Boards manufactured with the negative true TTL option are Fiber optics LED drivers designed such that a VMEbus logical one causes the output Stepping motor drivers driver to produce a logic one (high) to the user. Conversely, the positive true TTL option is designed such that a VMEbus logical one causes the output driver to produce a logic zero (low) to the user. Figure 1. VMIVME-2120 Functional Block Diagram 3 VMIVME-2120 64-bit High Voltage Digital Output with Built-in-Test General Description Features * The DS3668 quad-peripheral driver is designed for those Output fault protection applications (output options 0 through 2) where low operating High impedance TTL-compatible input power, high breakdown voltage, high output current, and low High output current -600mA per output output ON voltage are required. Unlike most peripheral drivers, a No output latch-up at 35V unique fault protection is incorporated on each output. When Low output ON voltage (550mV typical at 600mA) the load current exceeds 1.0A (approximately) on any output for High breakdown voltage (55V) more than a built-in delay time, nominally 25 ms, that output Open-collector outputs will be shut off by its protection circuitry with no effect on other Output clamp diodes for inductive flyback protection outputs. This condition will prevail until that protection circuitry NPN inputs for minimal input currents (1mA typical) is reset by toggling the corresponding input or the enable pin Low operating power low for at least 0.5 ms. The 25 ms built-in delay is provided to Standard 5V power supply ensure the protection circuitry is not triggered by turn-on surge Power up/down protection currents associated with certain kinds of loads. Fail-safe operation 2W power package The outputs are capable of sinking 600mA each and offer a 55V Pin-for-pin compatible with SN75437 breakdown. However, for inductive loads, the output should be clamped to 35V or less to avoid latch-up during turn-off (inductive flyback protection). An on-chip clamp diode capable of handling 800mA is provided at each output for this purpose. In addition, the driver incorporates circuitry that guarantees glitch-free power up or down operation and a fail-safe feature which puts the output in high impedance state when the input is open. * A DS3658 quad driver is also available. This device does not support the output fault protection described above. This is used with output options 3 through 5. 4 VMIVME-2120 64-bit High Voltage Digital Output with Built-in-Test Incandescent Lamp Driver Fault Conditions High incandescent lamp turn-on/inrush current can destroy In the event of a shorted load, shorted winding, or stalled motor, semiconductor lamp drivers and contributes to poor lamp the load current will attempt to increase. As described above, reliability. However, lamps with steady-state current ratings up the drive current to the output stage is diverted (limiting the load to 600mA can be driven with the UDN-2559EB without the need current to about 1A), causing the output stage to go linear. As for warming or current limiting resistors (not recommended). the junction temperature of the output stage increases, the thermal limit circuit will become operational, further decreasing When an incandescent lamp is initially turned ON, the cold lamp the drive current. The load current (junction temperature) is then filament is at minimum resistance and would normally allow a a function of ambient temperature, state of remaining drivers, 10 x to 12 x inrush current. With the UDN-2559EB, during turn- supply voltage, and load resistance. If the fault condition is on, the high inrush current is sensed by the internal low-value corrected, the output driver will return to its normal saturated sense resistor, drive current to the output stage is diverted by condition. the shunting transistor, and the load current is sensed by the internal low-value sense resistor, drive current to the output stage is diverted by the shunting transistor, and the load current Trademarks is limited to approximately 1A. During this short transition period, the output driver is driven in a linear fashion.

Inductive Load Driver Bifilar (unipolar) stepper motors can be driven directly. The internal flyback diodes prevent damage to the output transistors by suppressing the high voltage spikes which occur when turning OFF an inductive load. 5 VMIVME-2120 64-bit High Voltage Digital Output with Built-in-Test 1.
