SLLS849A – APRIL 2008 – REVISED MAY 2008 LOW-VOLTAGE HIGH-SPEED QUADRUPLE DIFFERENTIAL LINE RECEIVER WITH ±15-kV IEC ESD PROTECTION • Meets or Exceeds Standard TIA/EIA-422-B and ITU Recommendation V.11 • Operates From a Single 3.3-V Power Supply • ESD Protection for RS422 Bus Pins – ±15-kV Human-Body Model (HBM) – ±8-kV IEC61000-4-2, Contact Discharge – ±15-kV IEC61000-4-2, Air-Gap Discharge • Switching Rates up to 32 MHz • Low Power Dissipation: 27 mW Typ • Open-Circuit, Short-Circuit, and Terminated Fail-Safe • ±7-V Common-Mode Input Voltage Range With ±200-mV Sensitivity • Accepts 5-V Logic Inputs With 3.3-V Supply (Enable Inputs) • Input Hysteresis: 35 mV Typ • Pin-to-Pin Compatible With AM26C32, AM26LS32 • I off Supports Partial-Power-Down Mode Operation • Package Options: SOP, SOIC, TSSOP, QFN The AM26LV32E consists of quadruple differential line receivers with 3-state outputs. These differential receivers have ±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge) protection for RS422 bus pins. This device is designed to meet TIA/EIA-422-B and ITU recommendation V.11 drivers with reduced supply voltage. The device is optimized for balanced bus transmission at switching rates up to 32 MHz. The 3-state outputs permit connection directly to a bus-organized system. The AM26LV32E has an internal fail-safe circuitry that prevents the device from putting an unknown voltage signal at the receiver outputs. In the open fail-safe, shorted fail-safe, and terminated fail-safe, a high state is produced at the respective output. This device is supported for partial-power-down applications using Ioff. Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The AM26LV32EI is characterized for operation from –40 °C to 85°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
