TRSF23243 Datasheet 3-v To 5.5-v Dual Rs-232 Port

Manufacturer: Texas Instruments

Overview: www.ti.com.

General Description

/ORDERING INFORMATION The TRSF23243 consists of two ports, each containing three line drivers and five line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND).

This 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 drivers and receivers matches that needed for two typical serial ports used in an IBM PC/AT, or compatible.

Key Features

  • Single-Chip and Single-Supply Interface for Two IBM PC/AT Serial Ports.
  • Meets or Exceeds the 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 (ROUT2) Per Port.
  • Operates Up To 250 kbit/s.
  • Low Standby Current . . . 1 μA Typical.
  • External Capacitors . . . 4 × 0.22 μF.
  • Accepts 5-V Logic Input With 3.3-V Supply.
  • Allows for Flexible Po.
