MAX13451E - RS-485 Transceivers

Download the MAX13451E datasheet PDF. This datasheet also covers the MAX13450E variant, as both devices belong to the same rs-485 transceivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX13450E/MAX13451E are half-duplex and fullduplex RS-485/RS-422 transceivers.

These devices feature internal 100I and 120I termination resistors.

The resistor values are pin selectable.

Key Features

  • a logic inversion function. The logic inversion allows phase reversal of the A-B signals in case these are inadvertently connected wrongly. The MAX13450E/MAX13451E have 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. All driver outputs are protected to Q30kV ESD using the Human Body Model (HBM). The MAX13450E/MAX13451E are available in a 14-pin TSSOP package and operate over the automotive -40NC to +125NC temperature range. Resistors S Driver Drives 100I Doub.

These devices feature internal 100I and 120I termination resistors. The resistor values are pin selectable. A logic supply input allows interfacing to logic levels down to +1.8V. The MAX13450E/MAX13451E feature strong drivers specified to drive low-impedance lines found when a fully loaded bus, based on today’s 100I characteristic impedance cable, is doubly terminated. Both devices allow slew-rate limiting of the driver output to reduce EMI and reflections for data rates up to 500kbps.
