It operates across a 2V to 6V supply range, making it compatible with 5V logic systems as well as lower-voltage 3.3V buses when the supply allows. Each output can source or sink 7.8 mA, adequate for driving standard TTL loads or a few CMOS gate inputs. The -40°C to 85°C temperature grade suits industrial environments — factory floor controls, motor drive interface cards, or outdoor telecom line cards that see thermal cycling. ## Lifecycle and RoHS — the sourcing reality The part is RoHS non-compliant, containing lead in the solder finish. This prevents use in RoHS-exempted or EU-market assemblies. ## Package and handling note The through-hole package is hand-solder friendly but takes more board area than a surface-mount equivalent.","metaTitle":"SN74HC659NT 74HC Transceiver Inverting 3-State, 2V–6V","metaDescription":"SN74HC659NT 74HC transceiver with inverting 3-state outputs, 2V–6V supply, 7.8mA drive, -40°C to 85°C.

For a non-inverting transceiver, the SN74HC245N offers similar supply range and drive but different logic polarity. For higher speed or different supply voltage, the SN74ABT2245DW (4.5V, 32 mA) or SN74LVTH16245ADGVR (2.7V, 32 mA) are surface-mount alternatives — verify pinout and function before substituting."},{"question":"Is SN74HC659NT compatible with 5V logic?","answer":"Yes. The 2V to 6V supply range includes 5V, so the SN74HC659NT can be powered from a 5V rail and its inputs/outputs are 5V-compatible. The 7.8 mA output drive is sufficient for standard 5V TTL or CMOS loads."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HC659NT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HC659NT when reusing this data.
