description

The SN75126 quadruple line driver is designed to meet the IBM 360/370 I/O specification A22-6974-3. The output voltage is 3.11V minimum (at I_OH = -59.3 mA) over the recommended ranges of supply voltage (4.5V to 5.95V) and temperature. 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 SN75126 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 a low state and signals a fault condition by causing the fault-flag output to go low.

The SN75126 can drive a 50- load or a 90- load as used in many I/O systems. Optimum performance can be achieved when the device is used with either the SN75128 or SN75129 line receivers. Also, see the SN751730 for new 360/370 interface designs.

The SN75126 is characterized for operation from 0°C to 70°C.
