DESCRIPTION:
   The LS7272/LS7273 are short-circuit proof Quad Differential Industrial Power Line Drivers. They can operate up to 30V and have a selectable thermal shutdown features.

FEATURES:
• More feature-rich and cost-effective than the OL7272 and ET7273
• Pin to pin replaceable with the OL7272 and functionally equivalent to the ET7273
• Push-Pull or Open-Drain output drivers (LS7272)
• Open-Drain output drivers only (LS7273)
• Voltage Range: 4.5V – 30V (VDD – VSS)
• 120mA Sink/Source output drive
• Operating frequency up to 4 MHz
• Thermal shutdown protection for output driver overload
• Enable input with Thermal Shutdown disconnect feature
• 1.5A dynamic peak output current drive
• Outputs RS422A compatible
• Inputs CMOS/TTL compatible with hysteresis
• Output drivers fully connected or high-impedance state
