What this buffer does on the board
The Texas Instruments SN74LVC244ADWR is an octal buffer with non-inverting outputs and 3-state control, built on the 74LVC logic family. It operates from a 1.65 V to 3.6 V supply. The 3-state outputs let multiple buffers share a common data bus; the output-enable pins (active-low per element) put the outputs into high-impedance when deasserted, so the bus floats cleanly. The -40°C to 125°C operating range covers industrial enclosures and under-hood electronics that see temperature cycling, though this part lacks formal AEC-Q100 qualification — verify against your automotive-grade requirement if that applies.
Lifecycle and sourcing posture
The SN74LVC244ADWR carries an Active lifecycle status with ROHS3 compliance, so there is no last-time-buy pressure for new designs or ongoing production. The part is sourced and quoted to order against an RFQ.
Package and mounting
The 20-SOIC package (0.295-inch body width, 7.50 mm) is a standard surface-mount footprint shared across many 74LVC octal buffers. The Tape & Reel option (TR) suits automated pick-and-place; the Cut Tape (CT) option is available for prototype or small-batch builds. No special thermal management is needed — the 24 mA per channel stays within the SOIC's copper-land dissipation at 125°C ambient.
