74LS393
Description Each of these monolithic circuits contains eight masterslave flip-flops and additional gating to implement two individual four-bit counters in a single package. The DM74LS393 prises two independent four-bit binary counters each having a clear and a clock input. N-bit binary counters can be implemented with each package providing the capability of divide-by-256. The DM74LS393 has parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system-timing signals. Features s Dual version of the popular DM74LS93 s DM74LS393 dual 4-bit binary counter with individual clocks s Direct clear for each 4-bit counter s Dual 4-bit versions can significantly improve system densities by reducing counter package count by 50% s Typical maximum count frequency 35 MHz s Buffered outputs reduce possibility of collector mutation Ordering Code: Order Number DM74LS393M DM74LS373N Package Number M14A N14A Package Description 14-Lead Small...
