The MAX13450E/MAX13451E are half-duplex and full-duplex RS485/RS422 transceivers. These devices from Maxim feature internal 100 Ω and 120 Ω termination resistors whose values are pin-selectable. A logic supply input allows interfacing to logic levels down to +1,8 V.
The transceivers feature strong drivers specified to drive low-impedance lines found when a fully loaded bus, based on today’s 100 Ω 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 500 Kbps. The MAX13451E has a fault alarm indication output to signal to the system that an error condition exists in the driver. It also features a logic inversion function which allows phase reversal of the A-B signals in case these are inadvertently connected incorrectly.
