MAX3232IDWR TI RS-232 Transceiver | 16-SOIC | 3V-5.5V, 250kbps

Product Overview

The MAX3232IDWR from Texas Instruments is a dual RS-232 line driver/receiver with a ±15-kV ESD protection (HBM) on the RS-232 pins. It operates from a single 3-V to 5.5-V power supply, making it ideal for portable and space-constrained applications. The device features a proprietary low-dropout transmitter output stage that delivers true RS-232 performance from a 3-V supply using a dual charge-pump architecture. It requires only four external 0.1-µF capacitors for the charge pumps, saving board space. The MAX3232IDWR is offered in a 16-pin SOIC package and is fully compliant with TIA/EIA-232-F and ITU V.28 standards.
