PCA9517A
Level translating I2C-bus repeater
2. Features and benefits
2 channel, bidirectional buffer isolates capacitance and allows 400 pF on either side of
the device
Voltage level translation from 0.9 V to 5.5 V and from 2.7 V to 5.5 V
Footprint and functional replacement for PCA9515/15A
I2C-bus and SMBus compatible
Active HIGH 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 I2C-bus devices and multiple masters
Powered-off high-impedance I2C-bus pins
Port A operating supply voltage range of 0.9 V to 5.5 V
Port B operating supply voltage range of 2.7 V to 5.5 V
5 V tolerant I2C-bus and enable pins
0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be
less than 400 kHz because of the delays added by the repeater)
ESD protection exceeds 5500 V HBM per JESD22-A114 and 1000 V CDM per
JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
Packages offered: SO8, TSSOP8 and HWSON8

[1] Also known as MSOP8.
[2] PCA9517ADP/DG is functionally the same (electrically and mechanically) as the PCA9517ADP, but was initially produced (e.g., “born”)
with Dark Green (lead-free and halogen/antimony-free) package material and is a temporary unique orderable part number for
customers who desire to order and only receive Dark Green package material. The standard part PCA9517ADP will transition to Dark
Green package material in 2Q’12 and then the PCA9517ADP and PCA9517ADP/DG devices will be identical. The PCA9517ADP/DG
part number will be EOL after several years as customers who used this temporary part number update their BOM to the normal part
number.
