It has the same high speed performance of LSTTL combined with true COMS low power coumption. This counter circuit contai independent ripple carry counters and two 4-bit ripple carry binary counters, which can be cascated to create a single divide by 256 counter. Each 4-bit counter is incremented on the high to low traition (negative edge) of the clock input,and each has an independent clear input. When clear is set to low all four bits of each counter are set to a low level. This enables count truncation and allows the implementation od divide by N counter configuratio. All inputs are equipped with protection circuits agait static discharge and traient excess voltage. NC = No Internal Connection February 1993 1/12
