The MAX3362 is a low-power, high-speed, single +3.3V-powered RS-485/RS-422 transceiver. The device contains one differential transceiver consisting of a line driver and receiver. The transceiver operates at data rates up to 20Mbps, with an output skew of less than 6ns. Driver and receiver propagation delays are guaranteed below 50ns. This fast switching and low skew make the MAX3362 ideal for multidrop clock/data distribution applications. The output level is guaranteed at +1.5V with a standard 54Ω load, compliant with RS-485 specifications. The transceiver draws 1.7mA supply current when unloaded or fully loaded with the drivers disabled. Additionally, the MAX3362 has a low-power shutdown mode, reducing the supply current to 1µA. The MAX3362 has a 1/8-unit-load receiver input impedance, allowing up to 256 transceivers on the bus. The MAX3362 is designed for half-duplex communication. The device has a hot-swap feature that eliminates false transitions on the data cable during circuit initialization. The drivers are short-circuit current limited, and a thermal shutdown circuit protects against excessive power dissipation. The MAX3362 is available in an 8-pin SOT package and specified over industrial and automotive temperature ranges. Applications: Clock/Data Distribution, Telecom Equipment, Security Equipment, POS Equipment, Industrial Controls.
The MAX3362 is a low‑power, high‑speed transceiver designed for RS‑485/RS‑422 communication. It operates from a single +3.3 V supply, provides a guaranteed +1.5 V output level, and supports half‑duplex operation with up to 256 transceivers on the same bus.
Key features include a maximum data rate of 20 Mbps, a hot‑swap capability, short‑circuit current limiting, and a 1 pA low‑power shutdown mode. The device is offered in an 8‑pin SOT‑23 package and is qualified for both industrial and automotive temperature ranges.
