Each of the six buffer elements can source 2.6 mA and sink 24 mA, making it suitable for driving bus lines, LED indicators, or CMOS inputs on legacy 5V logic backplanes. The 3-state output control allows multiple devices to share a common data bus without contention. ## Active lifecycle — no near-term obsolescence concern It is ROHS3 compliant. This is a mature 74LS part that continues to serve legacy maintenance, repair, and low-volume production builds where 5V TTL-compatible logic is still required. ## Output drive and bus interfacing The 24 mA sink capability per output is the headline rating that matters for bus loading. It can drive up to ten standard 74LS loads (each at 0.4 mA input low current) with margin, or directly switch a small relay coil through a pull-up resistor. The 2.6 mA source current is lower — typical for 74LS totem-pole outputs — so when driving high-impedance CMOS inputs, a pull-up resistor to 5V is often added to improve noise margin and rise time. The 3-state enable control is active-low on this variant; verify the enable polarity against your bus controller's output enable signal. ## Package and handling for the rework bench The 16-pin DIP (0.300\" body width) is a through-hole package that hand-solders easily and survives repeated rework without pad lift. No moisture sensitivity level applies to hermetic DIP packages — no bake required before assembly. The 0.100\" pin pitch is standard for breadboard prototyping and legacy PCB layouts. When sourcing for a repair or retrofit, the DIP form factor means a direct drop-in replacement for any 16-pin DIP hex buffer in the same socket footprint.","metaTitle":"SN74LS365AN 74LS Hex Buffer, Non-Inverting, 3-State, 16-DIP","metaDescription":"Texas Instruments SN74LS365AN 74LS hex non-inverting buffer with 3-state outputs. 4.75V–5.25V supply, 2.6mA/24mA drive, 16-DIP.

The enable polarity also differs — the 365 uses active-low enables, the 366 uses active-high. Verify your bus logic polarity before substituting."},{"question":"What is the equivalent or replacement for SN74LS365AN?","answer":"The SN74LS645-1N is a functional alternative — it is an 8-bit non-inverting transceiver with 3-state outputs in a 20-pin DIP, but it provides bidirectional bus handling rather than the unidirectional buffer of the 365. For a direct pin-compatible replacement, stick with the SN74LS365AN or check the 74HCT365 series if 5V CMOS compatibility is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS365AN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS365AN when reusing this data.
