Maxim MAX13172E Datasheet

General Description

The MAX13172E is a four-driver/four-receiver multiproto­col transceiver that operates from a single +5V supply in
conjunction with the MAX13170E and MAX13174E. The
MAX13172E, along with the MAX13170E and the
MAX13174E, 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 MAX13172E transceiver
carries serial-interface control signaling, while the
MAX13170E carries the high-speed clock and data sig­nals. Typically, the MAX13170E is terminated using the
MAX13174E.

The MAX13172E is available in a 5.3mm x 10.2mm, 28­pin SSOP package and operates over the 0°C to +70°C
commercial temperature range.

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.
