| Manufacturer | Fairchild Semiconductor |
| Title | Decade and Binary Counters |
| Description | Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the DM74LS90. All of these counters have a gated zero reset and the DM74LS90 also has. |

| Title | DECADE COUNTER |
| Description | — The ’90 is a 4-stage ripple counter containing a high speed flip-flop acting as a divide-by-two and three flip-flops connected as a divideby-five counter. It can be connected to operate with a conventional BCD out put pattern or it can be connected to provide a 50% duty cycle output. In the BCD m. |
