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 b.
put. 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. 1QA NC 1QB NC 1QC 3 2 1 20 19 4 18 5 17 6 16 7 15 8 14 9 10 11 12 13 2CLR NC 2QA NC 2QB 1QD GND NC 2QD 2QC NC − No internal connection ORDERING INFORMATION TA PACKAGE† ORDERABLE PART NUMBER TOP-SIDE MARKING PDIP − N Tube of 25 SN74HC393N SN74HC393N Tube of 50 SN74HC393D SOIC − D Reel of 2500 Reel of 250 .
