P82B715TD,118

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
