A copy of it is embedded in the package 20-SOIC (0.295, 7.50mm Width). In this case, it is packaged in the same way as Tape & Reel (TR). In order to achieve this superior flexibility, 8-Bit circuits are used. A Universal Shift Register is the logic type of the electrical device that we are discussing. The electronic part is mounted in Surface Mount-direction. A higher operating temperature than -40°C~125°C is recommended. Featuring high and low output currents, 6mA 6mA offers maximum design versatility. This is a type of FPGA from the 74HC series. The supply voltage is 2V~6V. As it belongs to the 74HC299 family, it should be taken into consideration. In 20 terminations, a transmission line is terminated with an impedance-matched device. In order to maintain normal operation of the device, the supply voltage should remain above 5V. It is equipped with 20 pin count. An electronic part designed with 8 Bits is used in this product. It has 20 pins. The device belongs to the HC/UH family of electronic devices. At this point, Vsup reaches its maximum value. The supply voltage (Vsup) should be greater than 2V. It is configured with a trigger that uses POSITIVE EDGE. In addition to this, HOLD MODE; COMMON I/O PINS; TOTEMPOLE SERIAL SHIFT RIGHT & SHIFT LEFT OUTPUTS; GATED OUTPUT CONTROL is another characteristic of it.
