TL2218-285PWRG4 Overview
It is possible to terminate a transmission line with a device matching the impedance of the line, which is known as 20 termination. A well-known feature of the TSSOP is its low packaging cost. Materials used for packaging are the same as those used by Tape & Reel (TR). There are specific uses for the 20 pins. A 9 signal line is one that is exclusively used for transmitting signals or intelligence, or for public or private communication. Optimal efficiency requires a supply voltage of 4.75V. On it is a Surface Mount-mount. It is common for computers and other communication devices to use pronged contacts, called 20 pins. As the device can operate at supply voltages of 228mA, it is suitable for a wide range of applications. The system runs on a voltage of 3.5V as its minimum supply voltage. Voltage is maximum when 5.5V is maximal. The temperature should rise as a result of operating it. Therefore, to ensure maximum reliability, it operates at 125°C°C.
