74HCT299DB,112 Overview
Embedded in the 20-SSOP (0.209, 5.30mm Width) package, it is used by many applications. It is packaged in a way that resembles Tube. A 8-Bit-circuit is used to provide its superior flexibility. Logic type Universal Shift Register is used on this electrical device. As you can see from the image, this electronic component is mounted in a Surface Mount-direction. Operating temperatures should be higher than -40°C~125°C. As 6mA 6mA offers a high/low output current, it is versatile in terms of design. This is a type of FPGA from the 74HCT series. Using 4.5V~5.5V as a supply voltage, it operates. 74HCT299 family is represented by it. It is also possible to terminate a transmission line with a 20 termination, which is where the transmission line is closed with a device that matches the characteristic impedance of the transmission line. In order to function normally, the supply voltage should be higher than 5V. This device is equipped with 20 pins. A 8-Bit electronic part was designed for this application. Devices in this family are known as HCT devices. A maximum supply voltage (Vsup) is reached at 5.5V. It should be possible to exceed 4.5V with the supply voltage (Vsup). Power comes from a 5V source. It uses POSITIVE EDGE for its trigger. It is also characterized by HOLD MODE; COMMON I/O PINS; TOTEMPOLE SERIAL SHIFT RIGHT & SHIFT LEFT OUTPUTS; GATED OUTPUT CONTROL as another characteristic.
