Overview

The ICL3222EIVZ is a dual-channel RS-232 transceiver designed for 3V to 5.5V systems, offering robust 15kV ESD protection on the RS-232 I/O pins. It features an integrated charge pump that allows it to operate from a single supply using only four 0.1uF capacitors, making it ideal for space-constrained designs. The device also includes a 1uA low-power shutdown mode to preserve battery life in portable applications.

Why Choose This Part

This transceiver ensures a minimum data rate of 250kbps while providing 500mV of receiver hysteresis for superior noise immunity. It is a latch-up free, drop-in replacement for common industry standards like the MAX3222E, simplifying sourcing and hardware design.

Applications

Industrial Automation
Providing reliable serial communication between PLCs, sensors, and human-machine interfaces in electrically noisy environments.
Battery-Powered Handhelds
Utilizing the 1uA shutdown mode to maintain serial connectivity in portable diagnostics and data logging tools.
Embedded System Debugging
Acting as a level shifter between low-voltage microcontrollers (3.3V) and legacy RS-232 serial ports.
Point-of-Sale Terminals
Interfacing peripheral devices like barcode scanners or receipt printers with main processing units.

Getting Started

To implement this part, connect four 0.1uF charge pump capacitors to the C1-C4 pins and pull the SHDN pin high for normal operation. Ensure the VCC supply is bypassed with a local decoupling capacitor and verify that the 20-TSSOP land pattern matches your PCB footprint.
