Synchronous 4-Bit Counters

These synchronous, presettable Counters feature an internal carry look-ahead for application in high-speed counting designs. The '160, '162, 'LS160A, 'LS162A, and 'S162 are decade Counters and the '161, '163, 'LS161A, 'LS163A, and 'S163 are 4-bit binary Counters Synchronous operation is provided by having all Flip-Flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable inputs and internal gating. This mode of operation eliminates the output counting spikes that are normally associated with asynchronous (ripple clock) Counters however counting spikes may occur on the (RCO) ripple carry output. A buffered Clock input triggers the four Flip-Flops on the rising edge of the Clock input waveform. By Texas Instruments
