The Texas Instruments TRS211CDWR is a versatile 5V multichannel RS-232 line driver/receiver designed for interface applications. It provides the electrical interface between an asynchronous communication controller and a serial port connector.
This device integrates four line drivers and five line receivers, along with a dual charge-pump circuit that enables operation from a single 5V supply. It meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards. Key electrical features include operation at data signaling rates up to 120Kbps and a maximum driver output slew rate of 30V/µs. The device also incorporates ±15kV ESD protection on its bus-pin connections, exceeding the Human-Body Model (HBM) standard.
The TRS211CDWR includes shutdown (SHDN) and enable (EN) controls. In shutdown mode, supply current is reduced to a typical 1µA. The EN pin allows receiver outputs to enter a high-impedance state for wired-OR connections. The device is housed in a 28-pin SOIC package with a surface mount type and operates within a temperature range of 0°C to 70°C.
