SN54LS90 Datasheet, Equivalent, BINARY COUNTER.4-BIT BINARY COUNTER 4-BIT BINARY COUNTER |
| Part | SN54LS90 |
|---|---|
| Description | 4-BIT BINARY COUNTER |
| Feature | DECADE COUNTER; DIVIDE-BY-TWELVE COUNTER ; 4-BIT BINARY COUNTER
The SN54 / 74LS 90, SN54 / 74LS92 and SN54 / 74LS93 are high-speed 4-bit ripple type counters partitioned into two sections. Each cou nter has a divide-by-two section and ei ther a divide-by-five (LS90), divide-by -six (LS92) or divide-by-eight (LS93) s ection which are triggered by a HIGH-to -LOW transition on the clock inputs. Ea ch section can be used separately or ti ed together (Q to CP) to form BCD, bi-q uinary, modulo-12, or modulo-16 counter s. All of the counters have a 2-input g ated Master Reset (Clear), and the LS90 also has a 2- . |
