Input thresholds are 5V CMOS/TTL compatible; a 3.3V logic signal will not reliably cross the VIH(min) level at 5V VCC. If the design uses a mixed 3.3V/5V bus, a level-shifting buffer (such as the SN74LVTH series) is the correct choice. The 3-state output control (active-low output enable) lets multiple buffers share a common data bus without contention. ## Package and footprint The part comes in a 20-SSOP package — the narrow-body 5.3 mm wide variant with 0.65 mm pin pitch. This is a surface-mount package; no through-hole option exists for this order code. The shipping medium is Tape & Reel or Cut Tape, which suits both automated pick-and-place and small-quantity prototyping. ## Lifecycle and sourcing posture The part is ROHS3 compliant.","metaTitle":"SN74LV541ATDBR 74LV Buffer, 5.5V, 20-SSOP, Active","metaDescription":"Texas Instruments SN74LV541ATDBR is a non-inverting 3-state buffer from the 74LV series, 4.5V–5.5V supply, 16 mA output drive, -40°C to 125°C.
