Product details

12-bit asynchronous counter at 95 MHz

The SN74LV4040ADR is a 12-bit asynchronous binary counter from TI's 74LV low-voltage logic family. Asynchronous reset clears all 12 bits simultaneously, independent of the clock state. The asynchronous timing means the ripple delay through the counter chain accumulates across bits — the 95 MHz count rate is the maximum toggle at the clock input, not the propagation delay to the final output bit.

The tape-and-reel packaging option suits automated pick-and-place assembly for medium-to-high volume production runs.

Frequently asked questions

What is the count rate and trigger type of the SN74LV4040ADR?

The SN74LV4040ADR counts at 95 MHz on a negative-edge trigger. The asynchronous reset clears all 12 bits independent of the clock.
