The output voltage is 3.11 V minimum (at IOH = – 59.3 mA) over the recommended ranges of supply voltage (4.5 V to 5.95 V) and temperature (0°C to 70°C). Driver outputs use a fault-detection current-limit circuit to allow high drive current but still minimize power dissipation when the output is shorted to ground. The SN75130 is compatible with standard TTL logic and supply voltages. Fault-flag circuitry is designed to sense and signal a line short on any Y line. Upon detecting an output fault condition, the fault-flag circuit forces the driver output into the off (low) state and signals a fault condition by causing the fault-flag output to go low. The SN75130 can drive a 50-Ω load or a 90-Ω load as used in many I/O systems. Optimum performance can be achieved when the device is used wit...
