ICL3222ECAZ-T
Overview
The ICL3222ECAZ-T is a low-power, high-speed RS-232 transceiver designed for 3V to 5.5V systems. It features two transmitters and two receivers with a 1 microamp shutdown mode to extend battery life in portable applications. This device includes enhanced ESD protection up to 15kV on the RS-232 I/O pins.
Why Choose This Part
The IC operates efficiently at 0.3mA while supporting data rates suitable for high-speed serial protocols. Its wide supply voltage range of 3V to 5.5V ensures compatibility with both legacy 5V logic and modern low-voltage systems without requiring external level shifters.
Applications
Getting Started
To implement this device, place four 0.1uF capacitors for the internal charge pump and ensure the SHDN pin is pulled high for active operation. Engineers should verify the 0.65mm pitch SSOP-20 footprint for PCB layout and consider thermal relief for the ground plane.
