The PCA9515A is a dual bidirectional I2C-bus and SMBus voltage-level translator with an open-drain configuration. The PCA9515A requires a supply voltage between 1.8 and 5.5V, and it provides a guaranteed data rate of 400Kbps.

The PCA9515A is designed to address the issue of power supply noise and I2C-bus timing margins due to applications that require a voltage-level translator between two different power supply systems. The PCA9515A is a good choice when inter-system communication is required, since it offers both an open-drain configuration and a low-voltage supply. It also has a “burst mode”, in which data can be transferred for up to 8 bytes at a time.

The PCA9515A supports various features such as slew rate control, “bus free” detection, and a dedicated clock stretching input pin. The “bus free” detection feature prevents a false detection of a bus conflict when multiple devicesAre trying to use the same I2C-bus. The clock stretching feature helps prevent clock jitter or over-clock oscillations, and can be set for constant intervals. The DS10277689 data sheet also details how to customize the clock stretching range.

The PCA9515A offers two different options for controlling the voltage-level translator. The first option is an enable/disable pin that allows the user to control the direction of the PCA9515A via the ENB/DIS pin. The other option is the strobe enable (E) pin, which is used to control the direction of the voltage-level translator when interfacing with different power supplies. The E pin is also used in applications such as fan control or for communicating with peripheral devices.

The PCA9515A can be used in many different applications and can be used in a variety of different configurations. It can be configured as a combination of two I2C-bus ports and one SMBus port, or as single I2C-bus port. It can also be configured as a passive voltage-level translator, or an active voltage-level converter. It is also suitable for connections between devices that require different logic levels and speeds. The PCA9515A has an output enable/disable feature that allows the user to control the direction of the voltage-level translator.

The PCA9515A is a great choice for applications that require a voltage-level converter for I2C-bus or SMBus communication. It can be used in a variety of different configurations and it offers features such as “bus free” detection, clock stretching, and a dedicated enable/disable pin. The PCA9515A is robust and reliable, and is an excellent choice for applications requiring an I2C-bus or SMBus voltage-level translator.
