| Part | SN54LS290 |
|---|---|
| Description | DECADE COUNTER / 4-BIT BINARY COUNTER |
| Feature | DECADE COUNTER; 4-BIT BINARY COUNTER
The SN54 / 74LS290 and SN54/ 74LS293 are h igh-speed 4-bit ripple type counters pa rtitioned into two sections. Each count er has a divide-by-two section and eith er a divide-by-five (LS290) or divide-b y-eight (LS293) section which are trigg ered by a HIGH-to-LOW transition on the clock inputs. Each section can be used separately or tied together (Q to CP)t o form BCD, Bi-quinary, or Modulo-16 co unters. Both of the counters have a 2-i nput gated Master Reset (Clear), and th e LS290 also has a 2-input gated Master Set (Preset 9). SN54/74LS290 SN54/74L S293 DECADE C . |
