ST3241E is a serial interface chip produced by ST company. It has 3 drivers, 5 receivers and a dual charge-pump circuit. It meets the requirements of EIA/TIA and V.28/V.24 communication standards, providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±8KV USING IEC 1000-4-2 contact discharge and ±15KV using the Human Body Model. Receiver R2 is always active to implement a wake-up feature for serial port. The ST3241E has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. It is a complete serial port (3 drivers, 5 receivers) intended for notebook or subnotebook computers. Receivers R1 and R2 have extra outputs in addition to their standard outputs. These extra outputa are always active. Typical application are in notebook, subnotebook, palmtop computers, battery-powered equipment, hand-held equipment, peripherals and printers.
The ST3241E is a complete serial port device featuring three drivers and five receivers. It includes a dual charge-pump circuit to generate RS-232 output levels from a single 3V to 5.5V supply. The device offers enhanced electrostatic discharge (ESD) protection, rated at +8KV for contact discharge and +15KV for the human body model.
