MAX3292 - RS-485/RS-422 Transceivers

Download the MAX3292 datasheet PDF. This datasheet also covers the MAX3291 variant, as both devices belong to the same rs-485/rs-422 transceivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX3291/MAX3292 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.

Key Features

  • o Preemphasis Increases the Distance and Data Rate of Reliable RS-485/RS-422 Communication o Data Rate Optimized for 5Mbps to 10Mbps (MAX3291) Programmable up to 10Mbps (MAX3292) o 100nA Low-Current Shutdown Mode o Allow Up to 128 Transceivers on the Bus o -7V to +12V Common-Mode Input Voltage Range o Pin-Compatible with ’75180, MAX489, MAX491 MAX3080, MAX3083, MAX3086, MAX1482 _______________Ordering Information PART MAX3291CSD MAX3291CPD MAX3291ESD MAX3291EPD MAX3292CSD MAX3292CPD MAX3292ESD.

19-1405; Rev 1; 4/99 MAX3291/MAX3292 RS-485/RS-422 Transceivers with Preemphasis for High-Speed, Long-Distance Communication ________________General Description The MAX3291/MAX3292 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 MAX3291 is programmable for data rates of 5Mbps to 10Mbps, while the MAX3292 is programmable for data rates up to 10Mbps by using a single external resistor. The MAX3291/MAX3292 are full-duplex devices that operate from a single +5V supply and offer a low-current shutdown mode that reduces supply current to 100nA.
