P82B715

NXP Semiconductors

I²C-bus extender

7.2 Lx, Ly: buffered bus LDA or LCL

On the special low-impedance or buffered line side, the corresponding output at the Lx or

Ly pins becomes the LDA data line or LCL clock line.

7.3 V_CC, GND: positive and negative supply pins

The power supply voltages at each P82B715 used in a system are normally nominally the

same. If they differ by a signiﬁcant amount, noise margin may be sacriﬁced as the bus

HIGH level should not exceed the lowest of those supplies.

8. Application design-in information

By using two (or more) P82B715 ICs, a sub-system can be built that retains the interface

characteristics of a normal I²C-bus device so that the sub-system may be included in, or

added onto, any I²C-bus or related system.

The sub-system shown in Figure 5 features a low-impedance or buffered bus, capable of

driving large wiring capacitance.

The P82B715 will operate with a supply voltage from 3 V to 12.5 V but the logic signal

levels at Sx/Lx are independent of the chip’s supply. They remain at the levels presented

to the chip by the attached ICs. The maximum static I²C-bus sink current, 3 mA, ﬂowing in

either direction in the internal current sense resistor, causes a difference, or offset voltage,

less than 100 mV between the bus logic LOW levels at Sx and Lx. This makes P82B715

fully compatible with all logic signal drivers, including TTL. The P82B715 cannot modify

the bus logic signal voltage levels but it contains internal diodes connected between Lx/Sx

and V_CCthat will conduct and limit the logic signal swing if the applied logic levels would

have exceeded the supply voltage by more than 0.7 V. In normal applications external

pull-up resistors will pull the connected buses up to the desired voltage HIGH level.

Usually this will be the chip supply, V_CC, but for very low logic voltages it is necessary to

use a V_CCof at least 3.3 V and preferably even higher. Note that full performance over

temperature is only guaranteed from 4.5 V. Speciﬁcation de-ratings apply when its supply

voltage is reduced below 4.5 V. The absolute minimum V_CCis 3 V.
