MAX211CDB

Приемопередатчик RS232, 4 драйвера, 4.5В-5.5В, SSOP-28.

The MAX211CDB is a RS-232 multichannel Line Driver/Receiver consists of four line drivers, five line receivers and a dual charge-pump circuit. It has ±15kV 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 5V supply. The device operates at data signalling rate up to 120kbps and a maximum of 30V/µs driver output slew rate. The MAX211 has both shutdown (SHDN) and 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.
