When the output enable is inactive, the pins go high-impedance — no loading, no bus fight. This is the standard architecture for memory address buffers, peripheral chip-select fan-out, and multiplexed I/O lines in 8-bit microcontroller systems.","metaTitle":"SN74AHCT541N 74AHCT Buffer Non-Inverting, 3-State, 20-DIP","metaDescription":"TI SN74AHCT541N 8-bit buffer, 4.5V-5.5V supply, 8mA output, 3-state, through-hole 20-DIP.

It is not intended for 3.3V rails."},{"question":"What is the difference between SN74AHCT541N and SN74AHCT540N?","answer":"The SN74AHCT541N is a non-inverting buffer; the SN74AHCT540N is an inverting buffer. Both are 8-bit, 3-state, 20-DIP parts with the same supply and temperature range. The pinout differs on the output enable logic — verify the datasheet for your specific inversion requirement."},{"question":"What is the pinout of SN74AHCT541N?","answer":"The SN74AHCT541N uses a standard 20-pin DIP pinout. Pin 1 is output enable (active low), pins 2–9 are the data inputs (A1–A8), pins 11–18 are the outputs (Y1–Y8), pin 10 is GND, and pin 20 is VCC. The full pinout is in the Texas Instruments datasheet."},{"question":"What replaces SN74AHCT541N if I need a surface-mount version?","answer":"Texas Instruments offers the SN74AHCT541 in SOIC, SSOP, and TSSOP packages (e.g., SN74AHCT541DWR for SOIC-20). The electrical specs are identical — same 4.5V–5.5V supply, 8 mA drive, and -40°C to 125°C range. No functional replacement is needed; only the footprint changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHCT541N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHCT541N when reusing this data.
