MAXIM MAX3283EAUT+T

The MAX3280E/MAX3281E/MAX3283E/MAX3284E 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 MAX3280E/MAX3281E/MAX3283E/MAX3284E have true fail- safe circuitry, which guarantees 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 (high impedance). These devices feature 1/4- unit- load receiver input impedance, allowing up to 128 receivers on the same bus. The MAX3280E is a single receiver available in a 5- pin SOT23 package. The MAX3281E/MAX3283E single receivers have a receiver enable (EN or EN) function and are offered in a 6- pin SOT23 package. The MAX3284E features a voltage logic pin that allows compatibility with low- voltage logic levels, as in digital FPGAs/ASICs. On the MAX3284E, the voltage threshold for a logic high is user- defined by setting VL in the range from 1.65V to VCC. The MAX3284E is also offered in a 6- pin SOT23 package.
