The 3-state outputs allow multiple buffers to share a common data bus — the outputs go high-impedance when the output-enable pin is inactive, preventing bus contention. ## Lifecycle and compliance This part carries an Active lifecycle status with ROHS3 compliance. The ROHS3 rating means it meets the latest EU restriction levels for lead, mercury, cadmium, and phthalates, so it can be specified into new designs without a separate exemption review.","metaTitle":"SN74LVCH244APW 74LVCH Buffer, Non-Inverting, 1.65V-3.6V","metaDescription":"TI SN74LVCH244APW octal buffer with 3-state outputs, 24mA drive, 1.65V-3.6V supply.

The bus-hold circuit on each input eliminates the need for external pull-up or pull-down resistors on unused or floating inputs, which can simplify PCB layout and reduce component count in high-density designs."},{"question":"Is SN74LVCH244APW RoHS compliant?","answer":"Yes, it is ROHS3 compliant, meeting the latest EU RoHS directive restrictions."},{"question":"Is SN74LVCH244APW compatible with 3.3V logic?","answer":"Yes, the supply voltage range of 1.65V to 3.6V includes 3.3V, so it operates directly on a 3.3V rail and its output levels are compatible with standard 3.3V CMOS and TTL logic inputs."},{"question":"Can SN74LVCH244APW be used as a level shifter?","answer":"It can translate between supply voltage domains within its 1.65V to 3.6V range. For example, driving a 3.3V input from a 1.8V output is possible if the 1.8V supply is VCC and the receiving device's VIH is met. It is not a dedicated level shifter with direction control, but it serves in simple unidirectional voltage translation scenarios."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LVCH244APW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LVCH244APW when reusing this data.
