Pinout
The MAX3222IDBR is a 16-pin (SOIC package) dual-channel RS-232 transceiver. Key functions:
- Dual drivers/receivers for full-duplex communication.
- Supports ±15kV ESD protection on RS-232 lines.
- Operates from 3V to 5.5V, making it suitable for low-power applications.
- Features auto-shutdown to reduce power consumption when idle.
- Pinout includes T1OUT/T2OUT (transmitter outputs), R1IN/R2IN (receiver inputs), and VCC/GND for power.
Commonly used in serial communication interfaces (e.g., UART to RS-232 conversion).
