TCA9554DWT Overview
As far as the I/Os are concerned, it is programmed with 8.Packaging includes the device and the 16-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 1.65V~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 16 terminations in the fabric as a whole.There is voltage present at 1.8V as a result of the device.In order to run 260, we use the peak reflow temperature of this part.1 ports are available on the device in total.Depending on what family of CA9554 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.8 is the total number of bits on an IC chip.16 pins are present on the device.
