NCA9547A Product details

Description

The NCA9547A is an octal bidirectional translating multiplexer controlled by the I²C-bus.

Features

1-of-8 bidirectional translating multiplexers.
I²C-bus interface logic; compatible with SMBus standards.
Active LOW reset input.
Three address pins allowing up to eight 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.
