PCA9509 Product details

Description

The PCA9509 is a level translating I2C-bus/SMBus repeater that enables processor low voltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O.

Features

Bidirectional buffer isolates capacitance and allows 400 pF on port B of the device.
Voltage level translation from port A (1.35 V to VCC(B)  1.0 V) to port B (3.0 V to 5.5 V).
Requires no external pull-up resistors on lower voltage port A.
Active HIGH repeater enable input.
Open-drain inputs/outputs.
Lock-up free operation.
Supports arbitration and clock stretching across the repeater.
Accommodates Standard-mode and Fast-mode I2C-bus devices and multipl.
