... Outputs conform to the ANSI TIA/EIA-644 LVDS stan- dards. Flow-through pinout simplifies PC board layout and reduces crosstalk by separating the LVTTL/LVC- MOS inputs and LVDS outputs. The AS1156/AS1154 operates from a single +3.3V sup- ply and is specified for operation from -40 to +85°C. Figure 1. Block Diagram AS1156 ...
