The 74LS160 package, consisting of 16 pins, contains a single 4 bit synchronous counter circuit which can be wired for decade counting mod, without external logic chips. By wiring more than one 74LS160 together (cascading), it is possible to make higher count lengths (powers of ten). For example, two 74LS160 cascaded together would yield a counter capable of decimally counting the range 00 – 99.
