PCA9515A I2C 400KHz Dual Bidirectional Repeater Module

Features:

1. Dual Channel Bidirectional Buffer: This product contains two identical bidirectional open drain buffer circuits that extend I2C and similar bus systems without compromising system performance.
2. Active high enable (EN) input and internal pullup: The PCA9515A has an active-high enable (EN) input with an internal pullup, which allows the user to select when the repeater is active. This can be used To isolate a badly behaved slave on power-up reset.
3. Power-up control circuit: The device contains a power-up control circuit that sets an internal latch to prevent the output circuits from becoming active until VCC is at a valid level (VCC = 2.3 V).
4. Dual bus operation: The PCA9515A also can be used to run two buses: one at 5-V interface levels and the other at 3.3-V interface levels, or one at 400-kHz operating frequency and the other at 100-kHz operating If the two buses are operating at different frequencies, the 100-kHz bus must be isolated when the 400-kHz operation of the other bus is required. If the master is running at 400 kHz, the maximum system operating frequency may be less Than 400 kHz, because of the delays that are added by the repeater.
5. The output low levels for each internal buffer are approximately 0.5 V, but the input voltage of each internal buffer must be 70 mV or more below the output low level, when the output is driven low. This prevents a lockup condition from occurring when the input low condition is released.

Descriptions:

1. The PCA9515A is a BiCMOS integrated circuit intended
for I2C bus and SMBus systems applications. It operates from 2.3 V to
3.6 V VCC.
2. The PCA9515A buffers both the serial data (SDA) and
serial clock (SCL) signals on the I2C bus, while retaining all the
operating modes and features of the I2C system. This enables two buses
of 400-pF bus capacitance to be connected In an I2C application.
