Product Overview

The TRS3243ECDB is a RS-232 Line Driver/Receiver consists of three line drivers, five line receivers and a dual charge-pump circuit with ±15kV ESD (HBM and IEC61000-4-2, air-gap discharge) and ±8kV 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. This combination of driver and receiver matches that needed for the typical serial port used in an IBM PC/AT or compatible. The charge pump and four small external capacitors allow operation from a single 3 to 5.5V supply. In addition, the device includes an always-active non-inverting output (ROUT2B), which allows applications using the ring indicator to transmit data while the device is powered down. The device operates at data signalling rate up to 250kbps and a maximum of 30V/µs driver output slew rate.
  • Single-chip and single-supply interface for IBM PC/AT serial port
  • Always-active non-inverting receiver output (ROUT2B)
  • Serial-mouse driveability
  • Auto-power-down feature to disable driver outputs when no valid RS-232 signal is sensed
  • Designed to transmit at a data rate up to 500kbps
  • 1µA Typical Low standby current
  • 4 x 0.1µF External capacitors
  • Green product and no Sb/Br
