It contains two independent elements of four bits each, giving eight total buffer channels. The 3-state outputs allow the device to be placed on a shared bus without contention — when the output enable is inactive, the outputs go high-impedance and effectively disconnect from the bus. ## Output drive — 15 mA sink, 64 mA source The output current rating of 15 mA for a logic high and 64 mA for a logic low determines how many standard TTL or CMOS inputs this buffer can drive. At 64 mA sink capability, each output can handle a heavy fan-out of LS-TTL loads or drive a terminated backplane line. The asymmetric drive (stronger low than high) is typical of bipolar logic families and matters when interfacing to CMOS inputs that have different threshold voltages. ## Supply and temperature — 5 V nominal, commercial range Operating from a 4.5 V to 5.5 V supply, this buffer is designed for standard 5 V TTL systems. The 0°C to 70°C temperature grade limits it to commercial indoor environments — office equipment, test instruments, and controlled industrial enclosures. Not rated for automotive or extended industrial temperature ranges. ## Through-hole DIP — legacy and prototyping fit The 20-pin DIP (20-PDIP) package is a through-hole footprint that suits breadboard prototyping, socketed designs, and legacy PCB maintenance. It occupies more board area than a surface-mount SOIC or SSOP but is easier to hand-solder and replace in rework. For new high-density designs, a surface-mount 74AS variant would be the more space-efficient choice. ## Lifecycle — active, no LTB risk The SN74AS241AN carries an active lifecycle status, meaning Texas Instruments continues to manufacture it without a last-time-buy notice. This removes the sourcing risk for BOM lines that depend on a through-hole buffer in the 74AS family. ROHS3 compliance is confirmed, so it meets current environmental regulatory requirements.","metaTitle":"SN74AS241AN 74AS Buffer, Non-Inverting, 3-State, 20-DIP","metaDescription":"SN74AS241AN 74AS-series non-inverting buffer with 3-state outputs. 15mA/64mA drive, 4.5V-5.5V supply, 0°C-70°C.

The logic thresholds are TTL-compatible, so it interfaces directly with other 74AS, 74LS, 74ALS, and 74F families running at 5 V."},{"question":"What is the difference between SN74AS241 and SN74LS241?","answer":"The 74AS241 is the Advanced Schottky version of the octal buffer, offering higher speed (lower propagation delay) than the 74LS241 Low-Power Schottky variant. The 74AS family typically consumes more supply current but provides faster switching, which matters for high-frequency bus applications. Both are 5 V TTL families with the same pinout and function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AS241AN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AS241AN when reusing this data.
