Product Overview
The MAX232EIPWR from Texas Instruments is a dual RS-232 driver/receiver interface IC designed for serial communication. It operates from a single 5V power supply and features an integrated charge pump voltage converter that generates ±10V outputs from the 5V supply, eliminating the need for dual power supplies. The device meets all EIA-232-F and ITU V.28 specifications, making it ideal for portable and space-constrained applications. Housed in a compact 16-TSSOP package, it offers robust ESD protection up to ±15kV (HBM) on the RS-232 bus pins.
