Overview

The TRS3243E device consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge) protection on serial-port connection pins. The device meets the requirements of TIA/ EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.

  • Single-chip and single-supply interface for IBM™ PC/AT™ serial port
  • 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
  • Meets or exceeds requirements of TIA/EIA-232-F and ITU v.28 standards
  • Operates with 3-V to 5.5-V VCC supply
  • Always-active noninverting receiver output (ROUT2B)
  • Designed to transmit at a data rate up to 500 kbit/s
  • Low standby current: 1 μA typical
  • External capacitors: 4 × 0.1 μF
  • Accepts 5-V logic input with 3.3-V supply
  • Designed to be interchangeable with industry standard '3243E devices
