The LS161A/163A are high-speed 4-bit synchronous counters. They are edge-triggered, synchronously presettable, and cascadable MSI building blocks for counting, memory addressing, frequency division and other applications. The LS161A and LS163A count modulo 16 (binary).
The LS161A has an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock and all other control inputs. The LS163A has a Synchronous Reset (Clear) input that overrides all other control inputs, but is active only during the rising clock edge.
