SN74161N datasheet, a 25.6 KB PDF for the synchronous presettable 4-bit binary counter with asynchronous clear, supplied in plastic DIP (N suffix). It covers pin numbering, the count, load and clear function table, timing diagrams and DC characteristics. It is handy when diagnosing dividers, address counters or sequencers in vintage logic boards and arcade or test equipment. The 74161 and 74163 differ in clear behavior, so verify the chip marking before swapping.
