1 / 27 page SN54HC163, SN74HC163 4BIT SYNCHRONOUS BINARY COUNTERS SCLS298D − JANUARY 1996 − REVISED − OCTOBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Wide Operating Voltage Range of 2 V to 6 V D Outputs Can Drive Up To 10 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 14 ns D ±4-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Internal Look-Ahead for Fast Counting D Carry Output for n-Bit Cascading D Synchronous Counting D Synchronously Programmable description/ordering information These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The ’HC163 devices 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 instructed by the count-enable (ENP, ENT) inputs and internal gating. This mode of operation eliminates the output counting spikes normally associated with synchronous (ripple-clock) counters. A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform.
