General Description
The MXL1544/MAX3175 are four-driver/four-receiver
multiprotocol transceivers that operate from a single
+5V supply in conjunction with the MXL1543. The
MXL1544/MAX3175, along with the MXL1543 and
MXL1344A, form a complete software-selectable data
terminal equipment (DTE) or data communication
equipment (DCE) interface port that supports the V.28
(RS-232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A,
X.21, RS-423), and V.35 protocols. The MXL1544/
MAX3175 transceivers carry serial interface control sig-
naling, while the MXL1543 carries the high-speed clock
and data signals. Typically, the MXL1543 is terminated
using the MXL1344A. The MAX3175 is identical to the
MXL1544 except for the addition of a 10µs (typ) glitch
rejection circuit at the receiver inputs. The MXL1544/
MAX3175 are available in 28-pin SSOP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
