The P82B715TD,118 is an I2C-bus Extender intended for application in IC-bus and derivative bus systems. While retaining all the operating modes and features of the IC-bus it permits extension of the practical separation distance between components on the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines. The IC-bus capacitance limit of 400pF restricts practical communication distances to a few meters. Using this at each end of a long cable reduces that cables loading on the linked IC-buses by a factor of 10 and allows the total system capacitance load to be around 3000pF while the loading on each IC-bus on the Sx/Sy sides remains below 400pF. Longer cables, general-purpose wiring may be used to link IC-bus based modules without degrading noise margins.
Dual, bidirectional, unity voltage gain buffer with no external directional control required
Logic signal levels may include (but not exceed) both supply and ground
Logic signal input voltage levels are output without change and are independent of VCC
x10 Impedance transformation, but does not change logic voltage levels
Clock speeds to at least 100 and 400kHz when other system delays permit
ESD protection exceeds 2500V HBM per Mil. Std 883C-3015.7 and 400V MM per JESD22-A115
Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA
