The MxL83433 and MxL83434 are a family of monolithic quadruple differential line RS-485/RS-422 receivers that support communication up to 32Mbps in harsh industrial environments. The bus pins tolerate IEC electrical fast transients (EFT), IEC electrostatic discharge (ESD), offer a wide input voltage range, and input hysteresis.
Guaranteed low propagation delays and channel-to-channel and part-to-part propagation delay skews ensure maximum system performance.
A wide range of product options offers designers optimized solutions for their system. The eight product offerings include two package options, two temperature options, and two enable configurations to choose from. These options coupled with wide power supply range support (from 3.3V to 5V) provide a versatile portfolio that you can use in applications ranging from high-speed motor drives to wireless infrastructure and building automation. The integration of four receiver channels into compact TSSOP or NSOIC packages makes these products well suited for space-constrained enclosures that require robust, high-performance communication.
The MxL83433 device offers global enable pins, which allow all four channels to be enabled or disabled simultaneously. The MxL83434 device provide paired enable pins, allowing for the flexibility to control two channels at a time. Industry standard footprint and pinout ensure seamless compatibility for existing designs.
