The LTC1344A Chipset MXL1544/MAX3175, along with the MXL1543 and Chipset Operates from a Single +5V Supply MXL1344A, form a complete software-selectable data terminal equipment (DTE) or data communication Software-Selectable DCE/DTE equipment (DCE) interface port that supports the V.28 Supports V.28 (RS-232), V.10/V.11 (RS-449/V.36, (RS-232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A, X.21, RS-423), and V.35 protocols. The MXL1544/ EIA-530, EIA-530A, X.21, RS-423) Protocols MAX3175 transceivers carry serial interface control sig- Flow-Through Pin Configuration naling, while the MXL1543 carries the high-speed clock and data signals. Typically, the MXL1543 is terminated True Fail-Safe Operation using the MXL1344A. The MAX3175 is identical to the Low 0.5A Shutdown Current (No-Cable Mode) MXL1544 except for the addition of a 10s (typ) glitch rejection circuit at the receiver inputs. The MXL1544/ 10s Receiver Input Deglitching (MAX3175 Only) MAX3175 are available in 28-pin SSOP packages.

DD EE 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. ELECTRICAL CHARACTERISTICS (V = +5V, V = +6.8V, V = -5.6V, T = T to T , unless otherwise noted.
