DESCRIPTION/ ORDER INFORMATION
The MAX213 device consists of four line drivers, five line receivers, and a dual charge-pump circuit with 15-kV ESD protection pin to pin (serial-port connection pins, including GND). 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 5-V supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/us driver output slew rate. The MAX213 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 1 uA. Two receivers of the MAX213 are active during shutdown.
