概述
Description
The MAX3223EAP+ is a highly integrated RS-232 transceiver designed for communication between data terminal equipment (DTE) and data circuit-terminating equipment (DCE). Manufactured by Maxim Integrated, this IC is part of the MAX3223 series, utilizing a proprietary low dropout transmitter output stage, which enables true RS-232 performance from a 3.0V to 5.5V power supply. It features two drivers and two receivers facilitating full-duplex communication, and offers a data rate up to 250 kbps.
Key features include a low-power shutdown mode that reduces supply current to 1µA, an automatic power-down feature that activates when the circuitry senses no valid RS-232 signals, and an enhanced ESD protection of up to ±15kV on all RS-232 I/O pins. The device is ideal for portable applications due to its low power consumption, and it operates over the extended temperature range of -40°C to +85°C. It comes in a 20-pin SSOP package, making it suitable for space-constrained designs.
