The document details high-speed monolithic counters consisting of four d-c coupled master-slave flip-flops. These circuits are designed to provide either a divide-by-two and a divide-by-five counter (SN54176, SN74176) or a divide-by-two and a divide-by-eight counter (SN54177, SN74177). The devices are fully programmable, allowing outputs to be preset to any state by placing a low on the count/load input.
| Count Frequency (Clock-1) | 0 to 35 MHz |
|---|---|
| Count Frequency (Clock-2) | 0 to 17.5 MHz |
| Operating Temperature (SN54xx) | -55°C to 125°C |
| High-level Output Current | -800 µA |
| Low-level Output Current | 16 mA |
They function as a divide-by-two and a divide-by-five counter.
Yes, they can be used as 4-bit latches by using the count/load input as the strobe.
