The SN74AS869DW from Texas Instruments is a synchronous, presettable, 8-bit up/down counter designed for high-speed counting applications. It features internal-carry look-ahead circuitry, enabling cascading of counters without additional gating.
This counter operates synchronously, meaning all flip-flops are clocked simultaneously, preventing output counting spikes. It is fully programmable and can be preset to any number between 0 and 255. The load-input circuitry allows for parallel loading of cascaded counters, with loading being synchronous.
The device operates with a voltage supply range of 4.5V to 5.5V and has an operating temperature range of 0°C to 70°C. It is available in a 24-SOIC package, suitable for surface mounting.
Key features include a count rate of 45 MHz, synchronous reset, and positive edge triggering. The counter supports both up and down counting directions.
