ICL3222EIAZ-T
Overview
The ICL3222EIAZ-T is a high-speed RS-232 transceiver designed for 3.0V to 5.5V operation with integrated ESD protection up to 15kV. It features two drivers and two receivers, making it an ideal choice for space-constrained designs that require robust serial communication and low power consumption. The device includes a manual power-down mode that reduces supply current to just 1uA when the interface is inactive.
Why Choose This Part
This transceiver offers 15kV ESD protection on RS-232 I/O pins, significantly reducing the need for external protection components. It is a pin-compatible, low-power upgrade for older 5V MAX242E systems, allowing for easy modernization of existing designs.
Applications
Getting Started
When designing with this IC, ensure four 0.1uF charge pump capacitors are placed close to the pins for stable voltage conversion at 3.3V. Use the manual power-down pin (SHDN) to manage power consumption during idle periods, and monitor the receiver hysteresis to ensure signal integrity in high-noise applications.
