description

The SN75126 quadruple line driver is designed to

meet the IBM 360/370 I/O specification A22-6974-3.

The output voltage is 3.11 V minimum (at

H = high level,

L = low level,

X = irrelevant,

= –59.3 mA) over the recommended ranges of

supply voltage (4.5 V to 5.95 V) 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.

S = shorted to ground

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-Ω load or a 90-Ω 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.
