MAX3232ECPWR – 3-V-5.5-V Multichannel 250kbps Interface IC TSSOP-16

Resources:Datasheet
Multichannel RS-232 Transceiver IC with +-15kV ESD Protection for Reliable Serial Communication
The MAX3232ECPWR is a high-performance RS-232 transceiver designed for seamless serial communication between microcontrollers and RS-232 devices. Developed by Texas Instruments, this IC integrates two line drivers and two receivers, enabling full-duplex data transmission in embedded and industrial systems.
Operating from a single supply voltage range of 3 V to 5.5 V, the MAX3232ECPWR features an internal dual charge pump that generates the required RS-232 voltage levels using minimal external components. It complies with the TIA/EIA-232-F standard and provides robust +-15 kV IEC ESD protection across all interface pins. With data rates up to 250 kbps and controlled output slew rate to minimise EMI, this device is ideal for communication modules, industrial controllers, POS systems, and embedded serial interfaces.
