DM74LS161A • DM74LS163A Synchronous 4-Bit Binary Counters
General Description
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs.
T he D M74LS161A a nd D M74LS163A ar e 4- bit binary counters.
The carry output is decoded by means of a N OR ga te, thus pr eventing spi kes d uring th e n ormal counting mode of operation.
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs cha nge coincident w ith ea ch oth er when so instructed by th e co unt-enable i nputs and i nternal gating.
