FEATURES - - - - - - - - - Supply Voltage Range 3.5V to 30V Operation to 800KHz CMOS and TTL patible Inputs Separate logic bias and driver supply pins Optional single supply operation for moderate power applications High Impedance Buffered Inputs with Hysteresis may be driven directly by phototransistors Tri-State outputs 80m A peak SINK/SOURCE current Outputs Protected by Thermal Shut-Down APPLICATIONS - - Optical Encoders Industrial Controls DESCRIPTION These line drivers are pin patible 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 Vcc Bias pin. The output stages may then be powered by a separate supply at Vcc Drivers, 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 acplished at pin 8 which is directly connected to the ASIC substrate.
