MAX3291CPD

The MAX3291CPD high-speed RS-485/RS-422 transceivers feature driver preemphasis circuitry, which extends the distance and increases the data rate of reliable communication by reducing intersymbol interference (ISI) caused by long cables.The MAX3291CPD is programmable for data rates of 5Mbps to 10Mbps.

Features of the MAX3291CPD are:(1)preemphasis increases the distance and data rate of reliable rs-485/rs-422 communication;(2)data rate is optimized for 5mbps to 10mbps;(3)100na low-current shutdown mode;(4)allow up to 128 transceivers on the bus;(5)-7v to +12v common-mode input voltage range;(6)pin-compatible with '75180, max489, max491 max3080, max3083, max3086, max1482.Applications of the MAX3291CPD are:(1)long-distance, high-speed RS-485/RS-422;(2)communications;(3)telecommunications;(4)industrial-control local area networks.
