Description
- General description
- The PCA9507 is a 2-wire serial bus extender providing 3.3 V to 5 V level shift that allows up to 18 meters bus extension for reliable DDC, I2C-bus or SMBus applications. 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) line as well as the rise time accelerator on port A enabling the bus to drive a load up to 1400 pF or distance of 18 m on port A, and 400 pF
- on port B. Using the PCA9507 enables the system designer to isolate bus capacitance to meet HDMI DDC version 1.3 distance specification. The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PCA9507 is unpowered.
- Features
- 2 channel, bidirectional buffer isolates capacitance allowing 1400 pF on port A and 400 pF on port B
- Exceeds 18 meters (above the maximum distance for HDMI DDC)
- Rise time accelerator and normal I/O on port A
- Static level offset on port B
- Voltage level translation from 2.7 V to 5.5 V
- Upgrade replacement over PCA9517 for cable application
- I
- 2
- C-bus, SMBus and DDC-bus compatible
- Active HIGH buffer 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 2.7 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 5000 V HBM per JESD22-A114, 400 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: SO8 and TSSOP8
