It is not pin-compatible with the 4042BDC — the 4042BDC is a 4-function D latch in the 4000-series CMOS family — but it serves a similar storage/latching role in digital designs. For a direct 4000-series replacement, look at other 4042 variants (e.g., CD4042) with the same logic function and package style."},{"question":"What is the function of the 4042BDC?","answer":"The 4042BDC is a D latch with four independent latch functions. Each latch captures the logic level on its D input when the clock is active and holds that state until the clock toggles again. It is used for temporary data storage, register implementation, and control-bit latching in CMOS logic systems."},{"question":"How do I get current pricing and availability for 4042BDC?","answer":"Current pricing and availability are confirmed at the time of quote. Submit an RFQ through the distributor — the response will include the per-unit price, minimum order quantity, and estimated lead time based on real-time stock positions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/4042BDC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/4042BDC when reusing this data.
