Description PRESETTABLE 4-BIT BINARY UP/DOWN COUNTERS
Datasheet 54190 Datasheet54190 Datasheet (PDF)

PRESETTABLE BCD/DECADE UP/DOWN COUNTERS PRESETTABLE 4-BIT BINARY UP/DOWN COUNTERS The SN54 / 74LS190 is a synchronous UP/ DOWN BCD Decade (8421) Counter and the SN54/ 74LS191 is a synchronous UP / DOWN Modulo-16 Binary Counter. State changes of the counters are synchronous with the LOW-to-HIGH transition of the Clock Pulse input. An asynchronous Parallel Load (PL) input overrides counting and loads the data present on the Pn inputs into the flip-flops, which makes it possible to use the circuits.
