The counter triggers on both positive and negative clock edges, giving the designer a choice of rising-edge or falling-edge counting without external inversion. This dual-edge capability simplifies interfacing with sensors or other asynchronous signals.","metaTitle":"NXP 74HC4520D/S400118 Dual 4-Bit Binary Counter, 69 MHz","metaDescription":"NXP 74HC4520D/S400118 dual 4-bit binary counter, 69 MHz count rate, 2-6 V supply, -40 to +125°C, SO-16.
