ICL3225EIAZ
Overview
The ICL3225EIAZ is a high-speed, low-power RS-232 transceiver designed for 3.0V to 5.5V operation. It features two drivers and two receivers with integrated 15kV ESD protection and a 1Mbps guaranteed data rate, making it ideal for robust serial communication in modern embedded systems. The device includes enhanced automatic powerdown features that reduce standby current to just 1uA when the serial port is inactive.
Why Choose This Part
This transceiver offers a high data rate of 1Mbps with low skew and 15kV ESD protection on all RS-232 I/O pins. Its automatic powerdown feature reduces energy consumption without software overhead, and the on-chip charge pump only requires four small 0.1uF external capacitors.
Applications
Getting Started
To implement this device, connect four 0.1uF charge-pump capacitors between the C1/C2 pins and V+ / V- pins as specified in the datasheet. Monitor the Ready to Transmit (INVALID) output to detect the presence of a valid RS-232 signal at the receiver inputs. Ensure the 20-pin SSOP package is mounted with adequate decoupling on the Vcc line for stable operation at 1Mbps speeds.
