MAX13170ECAI+T Datasheet MAX13170ECAI+, MAX13170ECAI+T | P1-P3

General Description

The MAX13170E is a three-driver/three-receiver multipro-

tocol transceiver that operates from a +5V single supply.

The MAX13170E, along with the MAX13172E and the

MAX13174E, form a complete software-selectable data

terminal equipment (DTE) or data communication equip-

ment (DCE) interface port that supports the V.28 (RS-232),

V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A, X.21), and

V.35 protocols. The MAX13170E transceivers carry the

high-speed clock and data signals, while the MAX13172E

carry the control signals. The MAX13170E can be termi-

nated by the MAX13174E software-selectable resistor

termination network or by discrete termination networks.

The MAX13170E has an internal charge pump and a

proprietary low-dropout transmitter output stage that

allows V.11-, V.28-, and V.35-compliant operation from

a +5V single supply. The MAX13170E features a no-

cable mode that reduces supply current to 0.5µA, and

disables all (high-impedance) transmitter and receiver

outputs. Short-circuit current limiting and thermal shut-

down circuitry protect the receiver and transmitter out-

puts against excessive power dissipation. The

MAX13170E has extended ESD protection for all the

transmitter outputs and receivers inputs.

The MAX13170E is available in a 5.3mm x 10.2mm,

28-pin SSOP package and operates over the 0°C to

+70°C commercial temperature range.
