Bus driver in the AS family — what it does
The Texas Instruments SN74AS580N is a bus driver from the AS series, designed for high-speed bus-oriented systems where multiple outputs need to drive a common data path. The AS (Advanced Schottky) logic family delivers faster propagation delays than standard TTL while maintaining familiar supply and logic levels, making this part a drop-in upgrade for legacy bus-interface designs that need tighter timing margins.
RoHS non-compliant — check your assembly line
This part is RoHS non-compliant, meaning the lead finish and solderability profile are based on tin-lead (SnPb) alloys. For legacy or military/aerospace builds that still specify SnPb solder, it is the correct choice.
