It is a BUS DRIVER, AS SERIES part, meaning it delivers the higher speed and output drive of the AS logic family while maintaining TTL-compatible input thresholds. ## Lifecycle and RoHS — active but lead-bearing That is relevant for sustaining legacy designs that still use the AS logic family. This part is RoHS non-compliant, meaning the leads and internal terminations contain lead (Pb). If your assembly line or contract manufacturer runs RoHS-exempt (lead-bearing) profiles, this is a drop-in fit. For RoHS-only lines, you would need to source a lead-free equivalent or accept the exemption paperwork burden.","metaTitle":"SN74AS244N Bus Driver, AS Series, Active, RoHS Non-Compliant","metaDescription":"SN74AS244N is an active AS-series bus driver from Texas Instruments.

The AS variant is the choice when bus loading or propagation delay demands the extra performance; the LS variant draws less supply current. Both are octal buffers with the same pinout and function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AS244N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AS244N when reusing this data.
