Frequently Asked Questions

What is the maximum counting frequency of the SN74AS169AN?

The SN74AS169AN supports a maximum counting frequency of 75 MHz at nominal supply voltage with a 50 pF load capacitance, making it suitable for high-speed digital counting and sequencing applications in the AS logic family.

Can the SN74AS169AN count both up and down?

Yes, the SN74AS169AN is a bidirectional counter that supports both up and down counting directions. The count direction is controlled via a dedicated input pin, allowing flexible use in applications such as position tracking, motor control, and reversible event counting.

What is the TCO output on the SN74AS169AN used for?

The TCO (Terminal Count Output) on the SN74AS169AN signals when the counter reaches its terminal count (all 1s for up-counting or all 0s for down-counting). This output is used to cascade multiple SN74AS169AN devices together to form wider counters, enabling easy expansion beyond 4 bits in digital systems.

What package type does the SN74AS169AN come in, and is it suitable for breadboarding?

The SN74AS169AN is available in a 16-pin Dual-In-Line Package (DIP), which is through-hole and fully compatible with breadboards and prototype boards. This makes it convenient for development, testing, and educational projects requiring synchronous binary counting.
