MAXIM INTEGRATED / ANALOG DEVICES MAX3468CSA Differential Transceiver

The MAX3468CSA+ is a +5V fail-safe transceiver designed for PROFIBUS RS-485/RS-422 communication in an 8-pin NSOIC package. It operates at high speeds with a half-duplex differential bus capability, meeting standards such as TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27. The device provides a minimum output level of 2.1V with a 54-ohm load and supports data rates up to 40 Mbps. It includes one three-state differential line driver and one differential input receiver, both powered from a +5V supply. The transceiver features fail-safe circuitry that outputs a logic high when the receiver inputs are open or shorted, ensuring reliable operation on a terminated bus where all transmitters are disabled. Its receiver input impedance is 1/4 standard unit load, allowing up to 128 transceivers on the bus. The driver and receiver have active-high and active-low enable inputs, which can be connected externally for direction control. Applications include level translation, industrial communication, and networking. Key features include a supply voltage range of 4.75V to 5.25V, operating temperature from 0°C to 70°C, low propagation delays (15ns for the transmitter and 20ns for the receiver), low skew (2ns), and protections such as current limiting and thermal shutdown for overload conditions. The device supports multipoint transmissions over long or noisy lines, with low power consumption (shutdown current of 0.25μA and operating current of 2.5mA), along with enable, shutdown, and hot swap functionalities.
