If your system runs a 20 MHz bus, you've got 15 MHz of headroom before the counter misses an edge. The synchronous timing and dual positive/negative trigger type give flexibility for clock-domain crossing without adding external gate delay. Pair it with the asynchronous reset for deterministic power-up sequencing — the counter resets independent of the clock, which simplifies daisy-chain initialization in multi-stage divider chains. ## 16-SOIC footprint — what it connects to No exotic footprint, no via-in-pad requirement — just a straightforward reflow profile. The dual 4-bit elements pack two independent up counters in one body, saving board area compared to two single 4-bit counters in separate packages. ## Sourcing posture: quoted to order, not a spot gamble This part is active. We source it through franchised and independent distribution and confirm availability and current pricing at quote time.","metaTitle":"CD74HC4520MT 74HC Dual Binary Up Counter, 35 MHz, 16-SOIC","metaDescription":"TI CD74HC4520MT dual 4-bit binary up counter, 35 MHz count rate, 2 V to 6 V supply, -55°C to 125°C.

This gives predictable propagation delays and cleaner timing analysis in multi-stage designs."},{"question":"What is the closest functional alternative to CD74HC4520MT?","answer":"The CD74HCT390E is a through-hole, decade-counter variant in the 74HCT family with a 27 MHz count rate — slower and different logic type (decade vs binary), so it's not a pin-for-pin drop-in. For a surface-mount binary counter at 35 MHz, the CD74HC4520MT is the right fit; the HCT390E only makes sense if you need decade counting or through-hole mounting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC4520MT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC4520MT when reusing this data.
