MAX3175：+5V, Multiprotocol, Software-Selectable Control Transceivers

Forms a Complete Multiprotocol DCE or DTE Port with MXL1543 and MXL1344A

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 signaling, 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.
