I²C bus line buffer IC
BA8274 / F
BA8274 / F
BA8274, BA8274F are buffer ICs that can lengthen the bus line retaining all features and operating mode of I²C bus
system. Adoption of this buffer in data and clock line enable to improve the drive capacity and to lengthen the bus line
with using standard wire at a low price.
zApplications
Mini-component stereo, Micro-component stereo and Television.
zFeatures
1) Dual, bi-directional, unity voltage gain buffer.
2) I²C bus compatible.
3) 1:10 impedance transformation.
4) Logic signal levels may include both supply and ground.
