MAX3491E - 12Mbps and Slew-Rate-Limited True RS-485/RS-422 Transceivers

Download the MAX3491E datasheet PDF. This datasheet also covers the MAX3483E variant, as both devices belong to the same 12mbps and slew-rate-limited true rs-485/rs-422 transceivers family and are provided as variant models within a single manufacturer datasheet.

General Description

Devices in the MAX3483E family (MAX3483E/MAX3485E/ MAX3486E/MAX3488E/MAX3490E/MAX3491E) are ±15kV ESD-protected, +3.3V, low-power transceivers for RS-485 and RS-422 communications.

Each device contains one driver and one receiver.

MAX3483E/MAX3485E/ MAX3486E/MAX3488E/ MAX3490E/MAX3491E 3.3V-Powered, ±15kV ESD-Protected, 12Mbps and Slew-Rate-Limited True RS-485/RS-422 Transceivers General Description Devices in the MAX3483E family (MAX3483E/MAX3485E/ MAX3486E/MAX3488E/MAX3490E/MAX3491E) are ±15kV ESD-protected, +3.3V, low-power transceivers for RS-485 and RS-422 communications. Each device contains one driver and one receiver. The MAX3483E and MAX3488E feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. The partially slew-rate-limited MAX3486E transmits up to 2.5Mbps. The MAX3485E, MAX3490E, and MAX3491E transmit at up to 12Mbps.
