description
This synchronous, presettable 4-bit decade counter features an internal carry look-ahead circuitry for
application in high-speed counting designs. 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 ripple carry out output (RCO). A buffered clock input triggers the four flip-flops on the rising (positive-going) edge of the clock input waveform.

•Internal Look-Ahead for Fast Counting
•Carry Output for n-Bit Cascading
•Fully Synchronous Operation for Counting
•Flow-Through Architecture to Optimize PCB Layout
•Center-Pin VCCand GND Pin Configurations Minimize High-Speed Switching Noise
•EPIC(Enhanced-Performance Implanted CMOS) 1-µm Process
•500-mA Typical Latch-Up Immunity at 125°C
•Package Options Include Plastic Small-Outline Packages and Standard Plastic 300-mil DIPs
