WebFAST AND LS TTL DATA DUAL DECADE COUNTER; DUAL 4-STAGE BINARY COUNTER The SN54/74LS390 and SN54/74LS393 each contain a pair of high-speed 4-stage ripple counters. Each half of the LS390 is partitioned into a divide-by-two section and a divide-by five section, with a separate clock input for each section. WebFAST AND LS TTL DATA DECADE COUNTER; 4-BIT BINARY COUNTER The SN54/74LS290 and SN54/74LS293 are high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two sec-tion and either a divide-by-five (LS290) or divide-by-eight (LS293) section which are triggered by a HIGH-to-LOW transition on the clock inputs ... WebMar 29, 2024 · The 74LS90 BCD Counter is a very flexible counting circuit and can be used as a frequency divider or made to divide any whole number count from 0 to 9 for a single display. Cascading together two 74LS90 counters allows us to produce a 2-digit counter, but better still, using the dual decade/driver IC 74LS390 we can produce any combination of … iqbal love poetry
