1. general description the pca9515a is a cmos integrated circuit intended for application in i 2 c-bus and smbus systems. while retaining all the operating modes and features of the i 2 c-bus system, it permits extension of the i 2 c-bus by buffering both the data (sda) and the clock (scl) lines, thus enabling two buses of 400 pf. the i 2 c-bus capacitance limit of 400 pf restricts the number of devices and bus length. using the pca9515a enables the system designer to isolate two halves of a bus, thus more devices or longer length can be accommodated. it can also be used to run two buses, one at 5 v and the other at 3.3 v or a 400 khz and 100 khz bus, where the 100 khz bus is isolated when 400 khz operation of the other is required. two or more pca9515a s cannot be put in series. the pca9515a design does not allow this con?guration. since there is no direction pin, slightly different legal low voltage levels are used to avoid lock-up conditions between the input and the output. a regular low applied at the input of a pca9515a will be propagated as a buffered low with a slightly higher value. when this buffered low is applied to another pca9515a, pca9516a or pca9518/a in series, the second pca9515a, pca9516a or pca9518/a will not recognize it as a regular low and will not propagate it as a buffered low again. the pca9510/a, pca9511/a, pca9512/a, pca9513/a, pca9514/a cannot be used in series with the pca9515a, pca9516a or pca9518/a, but can be used in series with themselves since they use shifting instead of static offsets to avoid lock-up conditions. the output pull-down of each internal buffer is set for approximately 0.5 v, while the input threshold of each internal buffer is set about 0.07 v lower, when the output is internally driven low. this prevents a lock-up condition from occurring. 2. features n 2-channel, bidirectional buffer n i 2 c-bus and smbus compatible n active high repeater enable input n open-drain input/outputs n lock-up free operation n supports arbitration and clock stretching across the repeater n accommodates standard-mode and fast-mode i 2 c-bus devices and multiple masters n powered-off high-impedance i 2 c-bus pins n operating supply voltage range of 2.3 v to 3.6 v n 5.5 v tolerant i 2 c-bus and enable pins pca9515a i 2 c-bus repeater rev. 04 11 april 2008 product data sheet
