DESCRIPTION
These line drivers are pin compatible with 26LS31 in applications where pin 4 = 5V and pin 12 = GND. Internal
clamp diodes allow trouble-free operation when driving cable lengths exceeding 100m. Split supplies are provided
to minimize standby power dissipation in high voltage applications. The logic should be powered from a regulated
5V supply at the VccBias pin. The output stages may then be powered by a separate supply at VccDrivers, up to
30V. Output voltage swings of 0.3V to VCC-1.9V are typical. The outputs are protected against shorts to ground,
shorts to Vcc and to other outputs, by a two-fold scheme of current limiting and thermal shutdown. This assures
highly reliable operation in harsh environments.
The outputs may be placed into a high impedance state by application of a logic high at the EN- pin. For normal
operation, this pin should be at logic low or grounded.
