The 2V to 5.5V supply range lets this part bridge 3.3V and 5V domains without a level translator, provided the input thresholds align. The 8mA output drive per pin (both high and low) is enough for CMOS logic fan-out of 10–15 loads or driving a standard LED through a current-limiting resistor, but not for relays or high-current loads. For new designs, the 74AHC family remains a standard-logic workhorse; no immediate second-source concern, though the through-hole PDIP package is less common in high-volume surface-mount builds.","metaTitle":"SN74AHC244N TI 74AHC Buffer, Non-Inverting, 3-State, 20-DIP","metaDescription":"SN74AHC244N Texas Instruments 74AHC octal buffer with 3-state outputs, 2V–5.5V supply, -40°C to 125°C, 8mA drive, 20-PDIP.

Both are 3-state non-inverting octal buffers in the same 20-DIP footprint and share the same pinout. The AHC variant offers faster propagation delay and lower quiescent current at the same supply voltage, but check the input threshold levels — AHC uses CMOS thresholds, while HC uses TTL-compatible thresholds — which may matter in mixed-logic designs."},{"question":"Can SN74AHC244N drive LEDs directly?","answer":"Yes, each output can sink or source 8mA, which is sufficient to drive a standard LED with a series current-limiting resistor. For higher-current LEDs or multiple LEDs per output, an external transistor buffer is needed."},{"question":"Is SN74AHC244N RoHS compliant?","answer":"Yes, the SN74AHC244N is RoHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHC244N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHC244N when reusing this data.
