• 80mA peak SINK/SOURCE current
• Outputs Protected by Thermal Shut-Down
APPLICATIONS
• Optical Encoders
• Industrial Controls
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. Heat-sinking may be accomplished at pin 8 which is directly connected to the ASIC
substrate.
