RS-485 Transceivers with Integrated
100/120 Termination Resistors MAX13450E/MAX13451E
19-5254; Rev 1; 11/10
General Description
The MAX13450E/MAX13451E are half-duplex and full-
duplex RS-485/RS-422 transceivers. These devices fea-
ture 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.
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.
