P82B715

I²C-bus extender

Rev. 08 — 9 November 2009

Product data sheet

1. General description

The P82B715 is a bipolar IC intended for application in I²C-bus and derivative bus

systems. While retaining all the operating modes and features of the I²C-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 I²C-bus capacitance limit of 400 pF restricts practical communication distances to a

few meters. Using one P82B715 at each end of a long cable (connecting Lx/Ly to Lx/Ly)

reduces that cable’s loading on the linked I²C-buses by a factor of 10 and allows the total

system capacitance load (all devices, cable, connectors, and traces or wires connected to

the I²C-bus) to be around 3000 pF while the loading on each I²C-bus on the Sx/Sy sides

remains below 400 pF. Longer cables or low-cost, general-purpose wiring may be used to

link I²C-bus based modules without degrading noise margins. Multiple P82B715s can be

connected together, linking their Lx/Ly ports, in a star or multi-point architecture as long as

the total capacitance of the system is less than about 3000 pF and each bus at an Sx/Sy

connection is well below 400 pF. This conﬁguration, with the master and/or slave devices

attached to the Sx/Sy port of each P82B715, has full multi-master communication

capability. The P82B715 alone does not support voltage level translation, but it can be

simply implemented using low cost transistors when required. There is no restriction on

interconnecting the Sx/Sy I/Os, and, because the device output levels are always held

within 100 mV of input drive levels, P82B715 is compatible with bus buffers that use

voltage level offsets, e.g., PCA9511A, PCA9517, Sx/Sy side of P82B96.

The lower V_OLlevel and ability to operate with any master, slave or bus buffer is the

primary advantage of the using the P82B715 for long distance buses at the disadvantage

of not isolating bus capacitance like the P82B96 or PCA9600 are able to do. The primary

disadvantage of the P82B96 and PCA9600 is that the static level offset needed to isolate

bus capacitance does not allow these devices to operate with other bus buffers with

special offset levels or with master/slaves that require a V_ILlower than 0.8 V with noise

margin. A proven quick design-in point-to-point/multi-point circuit (Figure 9) is included in

Section 8.2 to allow rapid use of the P82B715 along with comparison waveforms so that

the designer can clearly see the trade-offs between the P82B715 and the

P82B96/PCA9600 and choose the type of device that is best for their application.

2. Features

I Dual, bidirectional, unity voltage gain buffer with no external directional control

required

I Compatible with I²C-bus and its derivatives SMBus, PMBus, DDC, etc.

I Logic signal levels may include (but not exceed) both supply and ground

I Logic signal input voltage levels are output without change and are independent of V_CC

I ×10 impedance transformation, but does not change logic voltage levels
