description

The SN75130 quadruple line driver is designed to meet the IBM 360/370 I/O specification GA22-6974-3. The

output voltage is 3.11 V minimum (at I = –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

The SN75130 is characterized for operation from 0°C to 70°C.

OUTPUTS

†

H = high level, L = low level, X = irrelevant,

S = shorted to ground

†

G and F are common to the four drivers.

If any of the four Y outputs is shorted, the

fault flag responds.
