DS91M047TMAX/NOPB

DS91M047 is a high-speed quad M-LVDS line driver designed to drive clock or data signals to up to four multipoint networks. M-LVDS (Multipoint LVDS) is a new family of bus interface devices based on LVDS technology, specifically designed for multipoint and multidrop cable and backplane applications. Unlike standard LVDS, it provides higher drive current to handle the dual termination required in multipoint applications. Controlled transition times minimize reflections commonly caused by unterminated stubs in multipoint configurations. The DS91M047 accepts LVTTL/LVCMOS input levels and converts them to M-LVDS signal levels with transition times greater than 1 ns. The device provides DE and DE inputs that are ANDed together to control the tri-state outputs. The DE and DE inputs are shared among all four drivers. The DS91M047 features a flow-through pinout for ease of PCB layout, offering a new solution for high-speed multipoint interface applications in a space-saving SOIC-16 package.
