Each of the two elements handles four bits, giving you eight channels in a single 20-SSOP package. Output drive is 16 mA per pin, sufficient for driving a short ribbon cable or a bank of LED indicators through a resistor. The 3-state outputs let you float the bus when the buffer is deselected, which is the standard trick for shared data or address lines in a multi-peripheral system. ## Supply voltage and logic compatibility — the 2V to 5.5V window The 2V to 5.5V supply range is the headline spec that decides fit. At 3.3V the SN74LV244ADBR works directly with a 3.3V MCU or FPGA bank; at 5V it interfaces with legacy 5V TTL or CMOS logic. The thresholds track the supply proportionally, so a 3.3V-powered buffer sees a VIH around 2.0V and a VIL around 0.8V — compatible with both 3.3V CMOS outputs and 5V TTL outputs that swing above 2.4V. If your design lives at 1.8V, this is not the part; you would step up to the 74AUC or 74LVC1G series. For the 2.5V to 5.5V band, though, the 74LV family is a proven workhorse. ## Temperature grade — industrial with a margin The 125°C ceiling is the junction limit for most low-voltage CMOS processes; staying within that keeps propagation delay and output drive within datasheet limits. ## Package and mounting — 20-SSOP surface-mount Surface-mount only — no through-hole variant in this listing. The Tape & Reel option (TR) is the production-pick-and-place format; the Cut Tape (CT) suits prototype or low-volume builds. ## Lifecycle — active and ROHS3 compliant No lead (Pb) exemption applies, so it is fully compatible with lead-free reflow profiles.","metaTitle":"SN74LV244ADBR Buffer, Non-Inverting, 2V-5.5V, 20-SSOP","metaDescription":"TI SN74LV244ADBR octal buffer with 3-state outputs.
