Description

**General description**
The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.
The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only one SCx/SDx channel can be selected at a time, determined by the contents of the programmable control register. The device powers up with Channel 0 connected, allowing immediate communication between the master and downstream devices on that channel.
**Features**
1-of-8 bidirectional translating multiplexer
I2C-bus interface logic; compatible with SMBus standards
Active LOW RESET input
3 address pins allowing up to 8 devices on the I2C-bus
Channel selection via I2C-bus, one channel at a time
Power-up with all channels deselected except Channel 0 which is connected
Low Ron multiplexers
Allows voltage level translation between 1.8 V, 2.5 V, 3.3 V and 5 V buses
No glitch on power-up
Supports hot insertion
Low standby current
Operating power supply voltage range of 2.3 V to 5.5 V
5 V tolerant inputs
0 Hz to 400 kHz clock frequency
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
Packages offered: SO24, TSSOP24, HVQFN24
