SN54LS190 Datasheet, Equivalent, UP/DOWN COUNTER.PRESETTABLE BCD/DECADE UP/DOWN COUNTER PRESETTABLE BCD/DECADE UP/DOWN COUNTER |
| Part | SN54LS190 |
|---|---|
| Description | PRESETTABLE BCD/DECADE UP/DOWN COUNTER |
| Feature | 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 as programmable counters. A Count Enable (CE) input serves as the carry / borrow input in multi-sta. |
