TI SNJ55ALS130J

The SN55ALS130 and SN75ALS130 quadruple line drivers are designed to meet the IBM 360/370 I/0 specification GA22-6974-3. The output voltage is 3.11 V minimum (at loH = -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 SN55ALS130 and SN75ALS130 are compatible with standard TTL logic and supply voltages. The SN55ALS130 and SN75ALS130 employ the IMPACT 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 SN55ALS130 and SN75ALS130 can drive a 50-Ω load as required in the IBM GA22-6974-3 specification or a 90-Ω load as used in many I/O systems. Optimum performance can be achieved when the devices are used with either the SN75125, SN75127, SN75128, or SN75129 line receivers. The SN55ALS130 is characterized for operation from -55 °C to 125 °C. The SN75ALS130 is characterized for operation from 0 °C to 70 °C
