DM74LS163AN 4-Bit Synchronous Counter For Timing Chains

DM74LS163AN is a dependable building block for counters and simple sequencers where you want outputs to change together and reduce decode glitches. It’s often used for clock division, step timing, and event tracking in control panels, fixtures, and older CPU-based designs. DM74LS163AN is a synchronous 4-bit binary counter with a preset feature, letting you start from a defined count and repeat cycles cleanly. It runs from 4.75 V to 5.25 V, supporting standard 5 V logic supplies. The carry look-ahead structure called out in the datasheet helps when you cascade counters for wider counts. Keep clock routing tight and avoid slow edges on enables. Request a quote for DM74LS163AN.
