Part Details:

SN54/74LS160ASN54/74LS161A BCD DECADE COUNTERS/ SN54/74LS162A 4-BIT BINARY COUNTERS SN54/74LS163A The LS160A / 161A / 162A / 163A are high-speed 4-bit synchronous count- ers. They are edge-triggered, synchronously presettable, and cascadableMSI building blocks for counting, memory addressing, frequency division andother applications. The LS160A and LS162A count modulo 10 (BCD). The BCD DECADE COUNTERS / LS161A and LS163A count modulo 16 (binary.) 4-BIT BINARY COUNTERS The LS160A and LS161A have an asynchronous Master Reset (Clear) input that overrides, and is independent of, the clock and all other control LOW POWER SCHOTTKY inputs. The LS162A and LS163A have a Synchronous Reset (Clear) input thatoverrides all other control inputs, but is active only during the rising clockedge.
