Detailed Description
The MXL1544/MAX3175 are four-driver/four-receiver
multiprotocol transceivers that operate from a single
+5V supply and the charge pump from the MXL1543.
The MXL1544/MAX3175, along with the MXL1543 and
MXL1344A, form a complete software-selectable DTE
or 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 or MAX3175
usually carries the control signals. The MXL1543 car-
ries the high-speed clock and data signals, and the
MXL1344A provides termination for the clock and data
signals.
The MXL1544/MAX3175 feature a 0.5μA no-cable
mode, true fail-safe operation, and thermal shutdown
circuitry. Thermal shutdown protects the drivers against
excessive power dissipation. When activated, the ther-
mal shutdown circuitry places the driver outputs into a
high-impedance state. The MAX3175 deglitching fea-
ture reduces errors in unterminated equipment.
The state of the mode-select pins M0, M1, and M2
determines which serial-interface protocol is selected
(Table 1). The state of the DCE/
DTE
input determines
whether the transceivers will be configured as a DTE
serial port or a DCE serial port. When the DCE/
DTE
input is logic HIGH, driver T3 is activated and receiver
R1 is disabled. When the DCE/
DTE
input is logic LOW,
driver T3 is disabled and receiver R1 is activated. The
INVERT pin state changes the DCE/
DTE
functionality
regarding T4 and R4 only. M0, M1, M2, INVERT, and
DCE/
DTE
are internally pulled up to V
CC
to ensure logic
HIGH if left unconnected.
