The part is specified as a decoder/demultiplexer. With the enable pin acting as a data input and the address lines selecting the output channel, it functions as a 1-of-4 demultiplexer. Each of the two independent circuits can route a signal to one of four outputs."},{"question":"What is the difference between SN74AHCT139PW and SN74HC139PW?","answer":"The key difference is the logic family. SN74AHCT139PW is from the 74AHCT series, which is pin-compatible with 74HC but uses TTL-compatible input thresholds. This means the AHCT variant can be driven directly by 5V TTL logic outputs without needing a pull-up, whereas the 74HC version uses CMOS thresholds."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHCT139PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHCT139PW when reusing this data.
