General 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. While retaining all the operating modes and features of the I2C-bus system during the level shifts, it also permits extension of the I2C-bus by providing bidirectional buffering for both the data (SDA) and the clock (SCL) lines, thus enabling the I2C-bus or SMBus maximum capacitance of 400 pF on the higher voltage side. The SDA and SCL pins are over-voltage tolerant and are high-impedance when the PCA9509 is unpowered.Features
â– Bidirectional buffer isolates capacitance andallows 400 pF on port B of the device
â– Voltage level translation from port A
(1 V to VCC(B) − 1.0 V) to port B (3.0 V to 5.5 V)
â– Requires no external pull-up resistors on lower voltage port A
â– Active HIGH repeater enable input
â– Open-drain inputs/outputs
â– Lock-up free operation
â– Supports arbitration and clock stretching across the repeater
â– Accommodates Standard-mode and Fast-mode I2C-bus devices
and multiple masters
â– Powered-off high-impedance I2C-bus pins
■Operating supply voltage range of 1.0 V to VCC(B) − 1.0 V on port A,
3.0 V to 5.5 V on port B
â– 5 V tolerant port B SCL, SDA and enable pins
â– 0 Hz to 400 kHz clock frequency
Remark: The maximum system operating frequency may be less than 400 kHz
because of the delays added by the repeater.
â– ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
JESD22-A115, and 1000 V CDM per JESD22-C101
â– Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
â– Packages offered: TSSOP8, SO8
