Synchronous 4-Bit Decade and Binary Counters
These synchronous, presettable, 4-bit decade and binary counters feature an internal carry look-
ahead circuitry for application in high-speed counting designs. The SN54ALS162B is a 4-bit
decade counter. The ‘ALS161B, ‘ALS163B, ‘AS161, and ‘AS163 devices are 4-bit binary counters.
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs
change coincidentally with each other when instructed by the count-enable (ENP, ENT) inputs and
internal gating. This mode of operation eliminates the output counting spikes normally associated
with asynchronous (ripple-clock) counters. A buffered clock (CLK) input triggers the four flip-flops on
the rising (positive-going) edge of the clock input waveform.
