PCA9513AD - NXP

Description: The PCA9513A and PCA9514A are hot swappable I2C-bus and SMBus buffers that allow I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9513A and PCA9514A provides bidirectional buffering, keeping the backplane and card capacitances isolated.

PCA9513AD Frequently Asked Questions (FAQs)

  • The PCA9513AD can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
  • While PCA9513AD is primarily designed for I2C bus level shifting, it can also be used for other communication protocols such as SPI, UART, or GPIO, but it's essential to ensure the protocol's voltage and current requirements are met.
  • To ensure reliable operation in noisy environments, it's recommended to use a bypass capacitor (e.g., 100 nF) between VCC and GND, and to keep the PCB layout clean and well-decoupled. Additionally, consider using a shielded cable or twisted pair wiring for the I2C bus.
  • The PCA9513AD can handle a maximum voltage difference of 5.5 V between the two sides of the level shifter. Exceeding this limit may damage the device.
  • Yes, PCA9513AD can be used to level shift between two I2C buses with different clock frequencies, but it's essential to ensure that the clock frequency of the target bus is within the device's supported frequency range (up to 1 MHz).
