There is no last-time-buy clock ticking, and no forced redesign to a newer logic family. The RoHS non-compliant marking is expected for this generation of 54F parts — they were designed before the lead-free transition, and the tin-lead finish is compatible with legacy solder profiles used in high-reliability rework and repair. ## Sourcing posture for the 54F192DMQB Because this is an active-production part in a mature logic family, it is available through both franchised and independent channels.","metaTitle":"54F192DMQB Decade Counter, Active, Bulk Package","metaDescription":"54F192DMQB is an active-production 54F-series decade counter in Bulk package.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.87","priceTiers":[{"qty":52,"price":"$5.87000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c22439748d88569822a316920ddbad22.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/54F192DMQB/alternatives.json"},"ai":{"faq":[{"question":"What is the function of the 54F192DMQB decade counter?","answer":"The 54F192DMQB is a synchronous up/down decade counter — it counts from 0 to 9 (or 9 to 0) on each clock pulse, with parallel load and asynchronous clear inputs. It is used in frequency division, event counting, and timing-chain applications in 54F-series logic systems."},{"question":"What are the direct equivalent or replacement parts for 54F192DMQB?","answer":"Functional equivalents in the same logic family include the 5493AFM (a 4-bit binary counter, not a decade counter) and the CY74FCT191ATSOC (a 74FCT-series binary up/down counter in a surface-mount package). Neither is a pin-for-pin drop-in; the 54F192DMQB is a unique decade-counter variant with a specific Bulk-package footprint."},{"question":"What is a decade counter?","answer":"A decade counter is a digital circuit that counts through ten distinct states (0 through 9) before resetting to zero. It is commonly used in frequency dividers, digital clocks, and event counters where a base-10 count sequence is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/54F192DMQB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/54F192DMQB when reusing this data.
