DESCRIPTION/ORDERING INFORMATION
2
This dual bidirectional I
C buffer is operational at 2.3-V to 3.6-V V
The PCA9515A is a BiCMOS integrated circuit intended for I
device contains two identical bidirectional open-drain buffer circuits that enable I
extended without degradation of system performance. Both buffers specifically are designed to support the
standard low-level-contention arbitration of the I
The PCA9515A buffers both the serial data (SDA) and serial clock (SCL) signals on the I
all the operating modes and features of the I
2
connected in an I
C application.
2
The I
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, accommodating more I
lengths.
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. It never
2
should change state during an I
C operation, because disabling during a bus operation hangs the bus, and
enabling part way through a bus cycle could confuse the I
state only when the global bus and the repeater port are in an idle state, to prevent system failures.
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 frequency. 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.
