SLLS016C - FEBRUARY 1986 - REVISED FEBRUARY 1993
The SN75ALS126 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 IOH = -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 SN75ALS126 is compatible with standard TTL logic and supply voltages.
The SN75ALS126 employs the IMPACTTM process to achieve fast switching speeds and low power dissipation. 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 SN75ALS126 can drive a 50- load as required in the IBM GA22-6974-3 specification or a 90- load as used in many I/O systems. Optimum performance can be achieved when the device is used with either the SN75127, SN75128, or SN75129 line receivers.
The SN75ALS126 is characterized for operation from 0°C to 70°C.
