MAX3237EIDB .

产品概述

The MAX3237EIDB is a RS-232 multichannel Line Driver/Receiver consists of five line drivers, three line receivers and a dual charge-pump circuit with ±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 3 to 5.5V supply. This device operates at data signalling rates of 250kbps in normal operating mode (MBAUD = GND) and 1Mbps when MBAUD=VCC. The driver output slew rate is a maximum of 30V/µs. The MAX3237E transmitter is disabled and the outputs are forced into high-impedance state when the device is in shutdown mode (SHDN=GND) and the supply current falls to less than 1µA. Also, during shutdown, the onboard charge pump is disabled, V+ is lowered to VCC and V- is raised toward GND.
