SN75C188NS TI RS-232 Interface IC | 4 Drivers, 5V Supply

Product Overview

The SN75C188NS from Texas Instruments is a quad RS-232 line driver designed for serial communication interfaces. It operates from a single 5V power supply and features four independent driver channels, each capable of converting TTL/CMOS logic levels to RS-232 voltage levels. The device is housed in an SOP-16 package, making it suitable for space-constrained applications. With a data rate of up to 120 kbps and built-in slew-rate limiting, the SN75C188NS ensures reliable data transmission in noisy environments.
