Description
The SN65C3222EPW is a dual-channel RS-232 line driver and receiver integrated circuit designed for communication applications. It is part of Texas Instruments' series of high-performance, low-power RS-232 devices. The device operates from a single 3.3V to 5.5V power supply, making it suitable for battery-powered and portable applications. It features automatic power-down when not in use, reducing power consumption.
Each driver converts TTL/CMOS input levels into RS-232 output levels, while each receiver converts RS-232 input levels into 5V TTL/CMOS levels. The SN65C3222EPW typically offers a data rate of up to 1 Mbps, which is suitable for various high-speed communication needs. It includes ESD protection up to ±15 kV on all RS-232 pins, ensuring robust performance against electrostatic discharge.
The device is packaged in a TSSOP (Thin Shrink Small Outline Package), labeled as "EPW," which is compact and space-efficient. This makes it an ideal choice for space-constrained applications in industrial, consumer, and computing environments.
