1 / 17 page SN54HC393, SN74HC393 DUAL 4-BIT BINARY COUNTERS SCLS143D – DECEMBER 1982 – REVISED JULY 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 = 13 ns D ±4-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Dual 4-Bit Binary Counters With Individual Clocks D Direct Clear for Each 4-Bit Counter D Can Significantly Improve System Densities by Reducing Counter Package Count by 50 Percent description/ordering information The ’HC393 devices contain eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. These devices comprise two independent 4-bit binary counters, each having a clear (CLR) and a clock (CLK) input. N-bit binary counters can be implemented with each package, providing the capability of divide by 256. The ’HC393 devices have parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.
