UM3486E - Union Semiconductor

UM3486E True RS-485 Transceivers

The UM3483E, UM3486E are 3V to 5.5V-powered, ±15kV ESD-protected, slew-rate-limited differential transceivers which provide full RS485 compatibility. Each part contains one driver and one receiver, which is designed for data transmission with extended common mode range (-7V to 12V). The UM3483E features slew-rate-limited driver which minimizes EMI and reduc.

Features

slew-rate-limited driver which minimizes EMI and reduces reflections resulted from improperly terminated cables. The UM3483E allows up to 500kbps error-free data transmission, while the partially slew-rate-limited UM3486E transmits at data rates up to 2.5Mbps. The UM3483E, UM3486E also feature enhanced electrostatic discharge (ESD) protection. All of the transmitter outputs and receiver inputs are protected to ±15kV using IEC61000-4-2 Air-Gap Discharge, ±15kV using the Human Body Model and ±8kV using IEC61000-4-2 Contact Discharge. Dr.
