Buffer selection note — 74LVC family, 3.3 V mixed-voltage bus
The Texas Instruments SN74LVC2244ADWR is a dual-element, 4-bit-per-element buffer with non-inverting logic and 3-state outputs, housed in a 20-SOIC package.
Supply range and temperature — industrial bus buffer
The 1.65V to 3.6V supply range covers both 1.8 V and 3.3 V rails, so you can use the same part on a dual-voltage board without a separate regulator for the buffer supply. The 3-state outputs let you share a data bus between multiple drivers — useful in memory-mapped peripheral systems where the bus needs to float when the buffer is deselected.
