Maxim MAX3284EAUT-T

ПриемникRS422, RS48552 Мбит/с

Overview

The MAX3280E/MAX3281E/MAX3283E/MAX3284EAUT 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/MAX3284EAUT 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 active-low EN) function and are offered in a 6-pin SOT23 package. The MAX3284EAUT 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 MAX3284EAUT is also offered in a 6-pin SOT23 package.
