Part SN54LS190
Description PRESETTABLE BCD/DECADE UP/DOWN COUNTER
Feature PRESETTABLE BCD/DECADE UP/DOWN COUNTERS PRESETTABLE 4-BIT BINARY UP/DOWN COUNTE RS 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 c hanges of the counters are synchronous with the LOW-to-HIGH transition of the Clock Pulse input.
An asynchronous Para llel Load (PL) input overrides counting and loads the data present on the Pn i nputs into the flip-flops, which makes it possible to use the circuits as prog rammable counters.
A Count Enable (CE) input serves as the carry / borrow inpu t in multi-sta .
