Each of the two elements counts four bits synchronously on the positive or negative clock edge, with an asynchronous reset per counter. ## 69 MHz count rate and dual-edge triggering The 69 MHz count rate is the headline speed spec — it tells you the maximum clock frequency the counter can accept while maintaining proper synchronous operation. If your incoming pulse train exceeds 69 MHz, this part will miss counts. The dual-edge trigger (positive or negative) gives flexibility: you can clock from a rising-edge sensor output or a falling-edge signal without external inversion. The asynchronous reset (active-high on each counter) lets you clear both counters independently without waiting for a clock edge, which simplifies power-on or fault-recovery sequencing. For dual-sourcing resilience, the 74HC4520 function is a standard 74HC logic function available from multiple vendors (Nexperia, TI, Toshiba, etc.) in the same SSOP-16 footprint, though pin-compatibility should be verified against the specific vendor datasheet.","metaTitle":"74HC4520DB,112 74HC Dual 4-Bit Binary Counter, 69 MHz","metaDescription":"Nexperia 74HC4520DB,112 dual 4-bit synchronous binary counter with asynchronous reset. 69 MHz count rate, 2 V to 6 V supply, -40°C to 125°C.
