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.
5) Power supply voltage range is large.
