The ST3243EBJR is an integrated circuit (IC) component manufactured by STMicroelectronics. It is a high-speed, three-driver, and five-receiver RS-232 transceiver IC.
Key features of the ST3243EBJR include:
1. Operation with a single power supply: The IC operates with a single +3.3V power supply, making it suitable for applications requiring low power consumption.
2. High-speed communication: The ST3243EBJR supports data rates up to 1Mbps, enabling efficient and fast transmission of data.
3. Integrated charge pumps: This IC incorporates integrated charge pumps that generate the necessary voltage levels for the RS-232 signal levels, eliminating the need for external level shifters.
4. ESD protection: The device offers excellent ESD protection, with ±15kV human body model (HBM) and ±8kV IEC61000-4-2 contact discharge.
5. Wide temperature range: It operates within a broad temperature range from -40°C to 85°C, making it suitable for industrial applications that demand operation in extreme environments.
6. Transmitter output short-circuit protection: The ST3243EBJR provides short-circuit current limiting and thermal shutdown to protect the transmitter outputs from excessive current or temperature.
7. Low power consumption in shutdown mode: With a low shutdown mode supply current of less than 1µA, this IC provides energy-efficient operation when not actively transmitting or receiving data
