Frequently Asked Questions
What is the maximum operating frequency of the SN74AS869DW?
The SN74AS869DW operates at clock frequencies up to 100 MHz typical, thanks to its Advanced Schottky TTL technology. This high-speed performance makes it suitable for demanding digital counting and timing applications in industrial and embedded systems.
Can the SN74AS869DW be cascaded to create wider counters?
Yes, the SN74AS869DW features active-low carry output (RCO) and borrow output (RBO) pins specifically designed for cascading. By connecting these outputs to the clock enable inputs of the next device, you can build 16-bit, 24-bit, or wider synchronous counters with minimal external logic.
What package does the SN74AS869DW come in and what are its pin dimensions?
The SN74AS869DW is packaged in a 20-pin SOIC (Small Outline Integrated Circuit) with a 300 mil body width and 1.27 mm pin pitch. This surface-mount package is compatible with standard reflow soldering processes and is well-suited for compact PCB designs.
What are common applications for the SN74AS869DW?
Common applications include digital event counters, frequency dividers, address generators in memory systems, motor position tracking with rotary encoders, programmable timers in industrial PLCs, and multi-stage counters in test and measurement instruments.
