The MAX13171E series is a multi-protocol serial interface chip launched by Texas Instruments. It supports V.28, V.10, V.11 and V.35 protocols. The chip integrates a charge pump and low-dropout transmitter output stage, which supports single-supply operation. The chip also has short-circuit current limiting and thermal shutdown circuits to protect the transmitter and receiver outputs from excessive power consumption. The MAX13171E series operates at a voltage range of +3.135V to +5.5V and a temperature range of -40°C to +85°C. The package is a 5mm x 7mm, 38-pin TQFN.
The MAX13171E, MAX13173E and MAX13175E form a complete pin‑selectable data terminal equipment (DTE) or data communication equipment (DCE) interface supporting V.28 (RS‑232), V.10/V.11 (RS‑449/RS‑36, RS‑530, RS‑530A, X.21) and V.35 protocols. The MAX13171E provides high‑speed clock and data signals, the MAX13173E supplies control signals, and the MAX13175E offers selectable termination networks.
The devices operate from a single supply (+3.135 V to +5.5 V), include an internal charge pump, low‑dropout output stages, no‑cable mode for reduced power, short‑circuit protection, thermal shutdown at +145 °C and extended ESD protection. They are offered in a 5 mm × 7 mm, 38‑pin TQFN package and are rated for –40 °C to +85 °C operation.
| Supply Voltage Range | +3.135 V to +5.5 V |
|---|---|
| Maximum Data Rate | 20/40 Mbps (max) |
| Package | 38‑Pin TQFN, 5 mm × 7 mm |
It supports V.28 (RS‑232), V.10/V.11 (RS‑449/RS‑36, RS‑530, RS‑530A, X.21) and V.35 protocols.
No‑cable mode reduces supply current and disables all transmitter and receiver outputs, placing them in high‑impedance.
Thermal shutdown protection activates at +145 °C.
The short‑circuit current limit is 150 mA.
