PCA9507D

The PCA9507D is an I²C-bus repeater and level translator designed by NXP Semiconductors. It is primarily used to bridge I²C-bus segments operating at different voltage levels, supporting bidirectional data transfer between systems. The device facilitates communication between lower voltage and higher voltage I²C buses, typically ranging from 0.8 V to 2.7 V on the low-side and 2.3 V to 5.5 V on the high-side.
Key features of the PCA9507D include a wide supply voltage range, low standby current, and the ability to handle clock stretching, arbitration, and synchronization on the I²C bus. It supports standard-mode, fast-mode, and fast-mode plus I²C speeds up to 1 MHz. The device also provides level shifting without the need for additional components like pull-up resistors, simplifying circuit design.
The PCA9507D is housed in a compact package suitable for space-constrained applications and is commonly used in consumer electronics, industrial systems, and automotive applications. Its robust design ensures reliable performance even in challenging environments, making it a versatile choice for engineers looking to implement I²C bus systems across different voltage domains.

The PCA9507D is a dual bidirectional translating I2C-bus/SMBus buffer. Key features include:
1. Dual I2C-bus/SMBus Channels: Supports two separate I2C bus lines for improved system design flexibility.

2. Voltage Level Translation: Facilitates level shifting between different voltage nodes, accommodating 1.0V to 5.5V on the A-side and 1.8V to 5.5V on the B-side.
3. Buffering for Load Isolation: Provides drive capability and signal isolation between I2C-bus segments, enabling longer bus lengths and more devices.
4. High-Speed Operation: Compatible with standard, fast, and fast-mode plus I2C-bus speeds, supporting up to 1 MHz.
5. Enable/Disable Functionality: Includes an active-high enable pin to isolate the bus when not in use, reducing power consumption and preventing bus contention.
6. Low Propagation Delay: Ensures quick signal transmission across channels, maintaining efficiency.
7. Operating Temperature: Suitable for industrial environments, with a range from -40°C to +85°C.
These features make the PCA9507D ideal for applications requiring flexible voltage interfacing and efficient I2C-bus communication.

The PCA9507D is typically available in a TSSOP (Thin Shrink Small Outline Package) type. This package is designed to be compact, suitable for surface mounting, and provides efficient thermal performance.

The PCA9507D is an I²C-bus repeater with a voltage-level translation feature, manufactured by NXP Semiconductors. It is commonly used to connect two segments of an I²C-bus, allowing them to operate at different voltage levels. The device supports bidirectional data transfer between bus segments at different voltage levels, making it suitable for interfacing between systems operating at different logic levels.
The PCA9507D comes in an 8-pin package. Here are the main pin functions:
1. A-side (VCCA, SDAn, SCLn): These pins are connected to the lower voltage I²C bus segment.
2. B-side (VCCB, SCLn, SDAn): These pins are connected to the higher voltage I²C bus segment.
3. GND: Ground pin.
4. EN: Enable pin to activate the device, allowing communication between both sides.
This device is specifically designed to provide voltage level translation between the A-side and B-side, with A-side supporting 0.8 V to 5.5 V and B-side supporting 2.3 V to 5.5 V. It is suitable for applications where interfacing devices or systems with different logic levels on the I²C bus is required.
