Additional Details

The SP232ACN utilizes an internal charge pump to generate the necessary ±10V RS-232 voltage levels from a single +5V supply. This eliminates the need for external high-voltage power supplies, simplifying system design and reducing cost. The device has a slew rate that is compliant with RS-232 standards, ensuring reliable data transmission. Its low power consumption makes it suitable for battery-powered applications. The SP232ACN is available in various packages, including SOIC and DIP. The device's robust design and compliance with industry standards make it a reliable choice for RS-232 communication in a wide range of applications. The transceiver can handle data rates up to 120 kbps. It also features a shutdown mode to further reduce power consumption when not in use. The SP232ACN is commonly used in applications where a standard RS-232 interface is required, such as connecting a microcontroller to a serial printer or modem.
