DESCRIPTION
The PCA9516 is a BiCMOS integrated circuit intended for
application in I
2
C and SMBus systems.
While retaining all the operating modes and features of the I
2
C
system, it permits extension of the I
2
C bus by buffering both the data
(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.
The I
2
C bus capacitance limit of 400 pF restricts the number of
devices and bus length. Using the PCA9516 enables the system
designer to divide the bus into five segments off of a hub where any
segment to segment transition sees only one repeater delay.
It can also be used to run different buses at 5 V and 3.3 V or
400 kHz and 100 kHz buses where the 100 kHz bus is isolated
when 400 kHz operation of the other bus is required.
FEATURES
5 channel, bi-directional buffer
I

C-bus and SMBus compatible
Active high individual repeater enable input
Open-drain input/outputs
Lock-up free operation
Supports arbitration and clock stretching across the repeater
Accommodates standard mode and fast mode I

ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115, and 1000 V CDM per
JESD22-C101.
Latch-up testing is done to JEDEC Standard JESD78 which
exceeds 100 mA.
