TRS232E - Dual RS-232 Driver and Receiver

Description

The TRS232E is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232F voltage levels from a single 5-V supply.

Each receiver converts TIA/RS-232-F inputs to 5V TTL/ CMOS levels.

Features

  • Meets or exceeds TIA/RS-232-F and ITU recommendation V.28.
  • Operates from a single 5V supply with 1μF chargepump capacitors.
  • Operates up to 250kbit/s.
  • Two drivers and two receivers.
  • ±30V Input levels.
  • Low supply current: 8mA typical.
  • ESD protection for RS-232 bus pins.
  • ±15-kV Human-body model (HBM).
  • ±8-kV IEC61000-4-2, Contact discharge.
  • ±15-kV IEC61000-4-2, Air-gap discharge 2.
