PCA9617ADPJ

The PCA9617ADPJ is a high-speed I2C-bus repeater designed by NXP Semiconductors. It enables bidirectional data transfer between its two sides, creating two isolated bus segments. This device is particularly useful for extending the range of I2C buses and accommodating different voltage levels between master and slave devices. Operating with a voltage range from 2.3V to 5.5V, the PCA9617ADPJ is ideal for applications demanding robust communication over longer distances.
Key features include support for fast-mode plus (Fm+) I2C speeds up to 1 MHz, ensuring high-speed data transfer. Its unique architecture prevents latch-up and reduces ground bounce, enhancing reliability. The device also provides level shifting capabilities, bridging devices operating at different logic levels. It's often used in consumer electronics, industrial control systems, and communication devices where stable and efficient data transfer is critical. The PCA9617ADPJ is encapsulated in a small, 8-pin TSSOP package, offering a compact solution for complex electronic systems.

The PCA9617ADPJ is a dual bidirectional buffer for I2C and SMBus applications. Equivalent products include the TCA9617A from Texas Instruments and the P82B96 from NXP. These chips serve similar purposes in signal buffering for I2C buses, supporting level translation and allowing for longer bus lines. Always check the datasheet for each alternative to ensure compatibility with your specific application requirements.

The PCA9617ADPJ is a dual bidirectional buffer specifically designed for I²C-bus and SMBus applications. It supports up to 1 MHz frequencies and features two open-drain I/O pins, which enable communication between multiple devices with differing bus operating voltages. The device provides level translation between 0.8 V to 5.5 V on the A-side and 2.2 V to 5.5 V on the B-side.
Key features include:
- Dual bidirectional buffer for I²C-bus and SMBus.
- Level shifting capabilities between different voltage levels.
- Supports data transfer up to 1 MHz.
- Low standby current.
- Active-high enable pin to disable the buffer when not in use, saving power.
- ESD protection for enhanced reliability.
- Compact TSSOP package for space-constrained applications.
The PCA9617ADPJ is suitable for applications requiring buffering and level translation, such as motherboard-to-daughterboard communication, or interfacing low-voltage microcontrollers with higher-voltage peripheral devices.

The PCA9617ADPJ is an I2C-bus repeater from NXP Semiconductors. It is designed to enable I2C-bus signals to be transmitted over longer distances or to facilitate interfacing between different voltage levels. The PCA9617ADPJ is housed in a TSSOP (Thin Shrink Small Outline Package) with 8 pins.
Here is a brief description of the pin functions:
1. VCC(A) (Pin 1): Power supply voltage for side A.
2. SDAA (Pin 2): Serial data line for side A.
3. SCLA (Pin 3): Serial clock line for side A.
4. GND (Pin 4): Ground.
5. SCLB (Pin 5): Serial clock line for side B.
6. SDAB (Pin 6): Serial data line for side B.
7. VCC(B) (Pin 7): Power supply voltage for side B; typically higher than VCC(A) for level translation.
8. EN (Pin 8): Enable pin to activate the repeater function.
The device allows for voltage translation between the two sides, and the enable pin controls whether the repeater is active, allowing for bus segmentation and isolation when needed.
