The DS91C176 and DS91D176 are high-speed M-LVDS differential transceivers designed for multipoint applications with multiple drivers or receivers. Multipoint LVDS (M-LVDS) is a new bus interface standard (TIA/EIA-899) based on LVDS but including several enhancements to improve multipoint performance. M-LVDS devices have superior drive capability and can support up to 32 loads. Along with increased drive, M-LVDS devices are required to have a controlled edge rate to minimize reflections and EMI. The 1 nSec minimum edge rate is tolerant of stub lengths up to 2 inches in length. M-LVDS devices also have a very large common mode range for additional noise margin in heavily loaded and noisy backplane environments. The DS91C176/DS91D176 are half-duplex transceivers that accept LVTTL/LVCMOS signals at the driver inputs and convert them to differential M-LVDS signal levels. The receiver inputs accept low voltage differential signals (LVDS,
