MAX3170 Datasheet | Maxim Integrated

Description The MAX3170 is a three-driver/three-receiver multiprotocol transceiver that operates from a +3.3V single supply. The MAX3170, along with the MAX3171/MAX3173 and MAX3172/MAX3174, form a plete softwareselectable data terminal equipment (DTE) or data munications equipment (DCE) interface port that supports the V.28 (RS-232), V.11 (RS-449/V.36, EIA530, EIA530-A, X.21), and V.35 protocols. The MAX3170 transceiver carries the high-speed clock and data signals, while the MAX3171 or MAX3173 carries the control signals. The MAX3170 can be terminated by the MAX3172 or MAX3174 software-selectable resistor termination network or by a discrete termination network. An internal charge pump and proprietary low-dropout transmitter output stage allow V.11-, V.28-, and V.35pliant operation from a +3.3V single supply. A nocable mode is entered when all mode pins (M0, M1, and M2) are pulled high or left unconnected. In nocable mode, supply current decreases to 1m A and all transmitter and receiver outputs are disabled (high impedance). Short-circuit limiting and thermal shutdown circuitry protect the drivers against excessive power dissipation. o 3V/5V Logic-patible I/O o Certified TBR-1 and TBR-2 pliant (NET1 and NET2)- Pending pletion o Supports V.28 (RS-232), V.11 (RS-449/V.36, EIA530, EIA530-A, X.21), and V.35 Protocols o Software-Selectable DTE/DCE o plete DTE/DCE Port with MAX3171/MAX3173 and MAX3172/MAX3174 o True Fail-Safe Receiver Operation o Available in Small 28-Pin SSOP Package o 10Mbps Operation (V.11/V.35) o Requires Only Four Tiny Surface-Mount Capacitors o All Transmitter Outputs Are Fault Protected to ±15V to Survive Cable Miswiring Features o Industry’s First +3.3V Single-Supply Transceiver ________________________Applications Data Networking CSU and DSU Data Routers PCI Cards Telemunications PART MAX3170CAI Ordering Information TEMP.
