It counts in binary up to its modulus on each clock edge, making it a standard building block for frequency division, event counting, and timing chains in digital logic designs. Onsemi lists this part as Active in production, so it remains a viable line-item for both new builds and repair stock without an immediate end-of-life clock. The 16-SOIC package is a surface-mount footprint that sits on a standard 1.27 mm pitch. The Bulk packaging means it ships in tubes or loose quantities rather than tape-and-reel, which matters for hand-assembly or low-volume rework where a feeder is not involved. ## RoHS compliance flag If your BOM requires full RoHS-10 conformance, this counter will not pass a restricted-substance audit without a waiver or an alternative part number. ## How it compares to the MC14040BDR2G The MC14040BDR2G is a 12-stage binary counter from the 4000B family with a 10 MHz count rate and asynchronous reset. The MC74AC163D is a 4-bit synchronous counter from the AC logic family, so it runs at higher speed and resets synchronously. They are not pin-compatible or drop-in replacements; the choice depends on whether the design needs a synchronous 4-bit counter or a 12-stage ripple counter.","metaTitle":"onsemi MC74AC163D Synchronous Binary Counter, 16-SOIC","metaDescription":"onsemi MC74AC163D synchronous binary counter in 16-SOIC.
