PCA9555DWG4 Product Details

PCA9555DWG4 Overview


As far as the I/Os are concerned, it is programmed with 16.Packaging includes the device and the SOIC.There are 24 terminations in the fabric as a whole.It is estimated that the part has 24 pins in total.There is voltage present at 3V as a result of the device.In order to run 260, we use the peak reflow temperature of this part.2 ports are available on the device in total.16 is the total number of bits on an IC chip.24 pins are present on the device.The chip conducts when the voltage supplied to it is 5.5V.A PARALLEL IO PORT, GENERAL PURPOSE uPs/uCs/Peripheral ICs belong to the class PARALLEL IO PORT, GENERAL PURPOSE uPs/uCs/Peripheral ICs.In the Parallel IO Ports series, it is one of the models.Upon reaching 85°C, the maximum operating temperature is reached.-40°C must be the minimum working temperature for this device.There is a maximum frequency of 400kHz for this chip.A frequency of 400kHz is an ideal frequency at which it can perform effectively.The 2 outputs are available for use.
