Analog Devices / Maxim Integrated MAX3280E/MAX3281E/MAX3283E/MAX3284E Receivers

Analog Devices MAX3280E/MAX3281E/MAX3283E/MAX3284E 52Mbps True Fail-Safe Receivers are single receivers designed for RS-485 and RS-422 communication. These devices guarantee data rates up to 52Mbps, even with a 3V power supply. Excellent propagation delay (15ns max) and package-to-package skew time (8ns max) make these devices ideal for multidrop clock distribution applications. The Analog Devices MAX3280E/MAX3281E/MAX3283E/MAX3284E have true fail-safe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are opened or shorted. The receiver output will be a logic high if all transmitters on a terminated bus are disabled. These devices feature 1/4-unit-load receiver input impedance, allowing up to 128 receivers on the same bus.
