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. 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. The MAX13451E has a FAULT alarm indication output to signal to the system that an error condition exists in the driver. The MAX13451E also features a logic inversion function. The logic inversion allows phase reversal of the A-B signals in case these are inadvertently connected wrongly. |
