What kind of level shifting does a pca9617a do?

What kind of level shifting does a pca9617a do?

The PCA9617A is a CMOS integrated circuit that provides level shifting between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) Fast-mode Plus (Fm+) I2C-bus or SMBus applications.

Is the pca9617a a low voltage repeater?

The PCA9617A contains two bidirectional open-drain buffers specifically designed to support up-translation/down-translation between the low voltage (as low as 0.8 V) and a 2.5 V, 3.3 V or 5 V I2C-bus or SMBus. All inputs and I/Os are overvoltage tolerant to 5.5 V even when the device is unpowered (VCC(B)and/or VCC(A)= 0 V).

Are there any authorized retailers for PCA Skin?

If you suspect that a seller is unauthorized, you can report them to us for investigation at [email protected] . Below is a list of websites that claim to sell PCA SKIN products, but do not have a relationship with PCA SKIN and are not authorized retailers.

What kind of wire harness does PCA make?

PCA has focuses on manufacturing integration and differentiates its services with in-house injection molding and over-molding as well as boot, terminal connector and single wire production capabilities. PCA manufactures a wide variety of wire harnesses that range from single circuit simplicity to three hundred plus circuit complexity.

Is the pca9617a a high impedance pin?

The SDA and SCL pins are overvoltage tolerant and are high-impedance when the PCA9617A is unpowered. The 2.2 V to 5.5 V bus port B drivers have the static level offset, while the adjustable voltage bus port A drivers eliminate the static offset voltage.

Which is the ground pin for the pca9685?

GND – This is the power and signal ground pin, must be connected VCC – This is the logic power pin, connect this to the logic level you want to use for the PCA9685 output, should be 3 – 5V max! It’s also used for the 10K pullups on SCL/SDA so unless you have your own pullups, have it match the microcontroller’s logic level too!

Where are the address jumpers on the pca9685?

This is done with the address jumpers on the upper right edge of the board. The I2C base address for each board is 0x40. The binary address that you program with the address jumpers is added to the base I2C address. To program the address offset, use a drop of solder to bridge the corresponding address jumper for each binary ‘1’ in the address.
