The LS160A is high-speed 4-bit synchronous counter. its edge-triggered, synchronously presettable, and cascadable MSI building blocks for counting, memory addressing, frequency division and other applications. The LS160A count modulo 10 (BCD). The LS160A have an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock and all other control inputs. Synchronous Counting and Loading Two Count Enable Inputs for High Speed Synchronous Expansion Terminal Count Fully Decoded Edge-Triggered Operation Typical Count Rate of 35 MHz ESD > 3500 Volts
