The MAX220CSE is an integrated circuit (IC) component that belongs to the MAX220 family of RS-232 interface ICs. It is a high-performance, dual driver/receiver IC designed specifically for serial communication applications, providing a low-cost, efficient solution.
One of the key features of the MAX220CSE is its capability to convert UART/CMOS levels to RS-232 levels and vice versa. It contains two drivers and two receivers, making it suitable for full-duplex communication. The drivers can handle data rates up to 120kbps, ensuring reliable and efficient data transmission.
The IC has low power consumption, typically drawing only 120μA in shutdown mode. This makes it ideal for portable devices or applications where power efficiency is crucial. Additionally, the MAX220CSE operates over a wide supply voltage range of +4.5V to +5.5V, providing flexibility in powering the device.
To protect the IC and connected devices, the MAX220CSE includes several important features. It has a ±5kV ESD (Electrostatic Discharge) protection on the RS-232 input/output pins, safeguarding against voltage spikes or electrostatic discharges. This feature ensures the longevity and reliability of the component and the devices it interfaces with.
Another notable feature of the MAX220CSE is its integrated charge pump circuitry
