The TRS213E consists of four line drivers, five line receivers, and a dual charge-pump circuit with ±15kV IEC ESD protection on the RS-232 bus 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. The charge pump and four small external capacitors allow operation from a single 5V supply. The devices operate at data signaling rates up to 120kbit/s and a maximum of 30V/µs driver output slew rate.
The TRS213E has an active-low shutdown (SHDN) and an active-high enable control (EN). In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, V– is pulled to GND, and the transmitter outputs are disabled. This reduces supply current typically to 1µA. Two receivers of the TRS213E are active during shutdown.
