Product Summary

The ST3243EB is a Transceiver with Auto-Powerdown. It consists of 3 drivers, 5 receivers and a dual charge-pump circuit. The ST3243EB device meets the requirements of EIA/TIA and V.28/V.24 comunication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver input are protected to ±8KV USING IEC 1000-4-2 contact discharge and ±15KV using the Human Body Model. The receiver R2 is always active to implement a wake-up feature for serial port.
