MAX3186CWP+

Overview

The MAX3186CWP+ is a complete DCE RS-232 serial port transceiver designed for modem applications. It features five drivers and three receivers without requiring external charge pumps. The device operates with VCC at +4.5V to +5.5V, VDD at +10.8V to +13.2V, and VSS at -10.8V to -13.2V. It guarantees data rates up to 230kbps and provides ±15kV ESD protection via the Human Body Model. Supply currents are less than 300µA for IDD and ISS, and less than 1mA for ICC. It is housed in a 20-pin SO package and functions within an operating temperature range of 0°C to +70°C.
