445  74LS  SYNCHRONOUS 4BIT UP/DOWN COUNTER SYNCHRONOUS 4BIT UP/DOWN COUNTER The SN54 / 74LS669 is a synchronous 4bit up/down counter. The LS669 is a 4bit binary counter. For high speed counting applications, this presettable counter features an internal carry lookahead for cascading purposes. By clocking all flipflops simultaneously so the outputs change coincident with each other (when instructed to do so by the co
