Synchronously programmable Internal look-ahead for fast counting Carry output for n-bit cascading Synchronous counting Load control line Diode-clampe.
without additional gating Instrumental in accomplishing this function are two count-enable inputs and a ripple carry out.
These synchronous presettable counters feature an internal carry look-ahead for application in high-speed counting designs The LS161A and LS163A are 4-bit binary counters The carry output is decoded by means of a NOR gate thus preventing spikes durin.
