Texas Instruments TRS213E RS-232 Line Driver/Receiver
Texas Instruments TRS213E RS-232 Line Driver/Receiver consists of five line receivers, four line drivers, and a dual charge-pump circuit with ±15kV IEC ESD protection on the RS-232 bus pins. The device provides the electrical interface between the serial port connector and an asynchronous communication controller and meets the requirements of TIA/EIA-232-F. Four small external capacitors and the charge pump allow operation from a single 5V supply. The devices operate at a maximum of 30V/µs driver output slew rate and data signaling rates up to 120kbit/s.
The Texas Instruments TRS213E has an active-high enable control (EN) and an active-low shutdown (SHDN). 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 feature reduces supply current typically to 1µA. Two receivers of the TRS213E are active during shutdown.
