CAT9555WI-T1 Product Details

CAT9555WI-T1 Overview


As far as the I/Os are concerned, it is programmed with 16.Packaging includes the device and the 24-SOIC (0.295, 7.50mm Width).As a matter of fact, it is available in the Tape & Reel (TR) case as well.Voting is done within 2.3V~5.5V hours after the order is placed.Surface Mount mounting is the type of mounting that is recommended for it.Devices work when their operating temperature falls within a certain range, called -40°C~85°C.For the performance of the output frequency, it works at 400kHz.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 NOT SPECIFIED, we use the peak reflow temperature of this part.2 ports are available on the device in total.Depending on what family of CAT9555 the part belongs to, you might be able to find related parts.With the help of this device, it is also possible to establish POR.16 is the total number of bits on an IC chip.As a result, the power can be delivered at 2.5/5V.24 pins are present on the device.It is important to note that 50mA is the maximum current that can be supplied to the device.
