SCM3406ASA

SCM3406ASA is a half-duplex enhanced transceiver designed for RS–485 data bus networks. Powered by 3VDC-5.5VDC supply, the SCM3406ASA
is fully compliant with TIA/EIA-485A standard and is suitable for data transmission of up to 10 Mbps. Receivers have an exceptionally high input
impedance, which places only 1/8 of the standard load on a shared bus and up to 256 transceivers .
The reliability design of A B pin is emphasized, including driver output over current protection and enhanced ESD design. The ESD protection level of
A,B pin can be up to 15kV (Human Body Model).

• 3.0-5.5V single supply operation
• Baud Rate Up to 10 Mbps
• 1/8 Unit Load—Up to 256 Nodes on a Bus
• Bus-Pin ESD Protection Up to 15 kV
• Driver short circuit protection
