OUTPUTS
The SN75ALS130 quadruple line driver is

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
SN75ALS130 is compatible with standard TTL
logic and supply voltages.
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 will respond.
†
The SN75ALS130 employs 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 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 SN75ALS130 is characterized for operation from 0°C to 70°C.
