DM74LS161A counters equivalent, synchronous 4-bit binary counters.
s Synchronously programmable s Internal look-ahead for fast counting s Carry output for n-bit cascading s Synchronous counting s Load control line s Diode-clamped inputs .
without additional gating. Instrumental in accomplishing this function are two count-enable inputs and a ripple carry ou.
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed counting designs. The DM74LS161A and DM74LS163A are 4-bit binary counters. The carry output is decoded by means of a NOR gate, thus preventing .
