SN74ALS666NT Overview


In the 24-DIP (0.300, 7.62mm) package, it is embedded. Tube is the way it is packaged. In this configuration, the output is set to Tri-State. There is a logic type of D-Type Transparent Latch for this electrical device. Based on the way of Through Hole, this electronic part is mounted. There is no supply voltage for this device. A temperature of 0°C~70°C is used for operation. The 74ALS series of FPGAs is the one this FPGA belongs to. It is designed with 8 bits. As far as this device is concerned, it has no terminations. It belongs to 74ALS666 family. In order to operate it, the supply voltage must be 5V. There are 24 pins attached to it. ALS is the family name of this electronic device. 24 pins are used in its design. The electronic part is mounted in a way that corresponds to Through Hole. This device is equipped with 2 ports. Subcategory Bus Driver/Transceiver contains this part. The device is powered by 5V power supplies. Electronic circuits are represented by 8 input lines. The 24mA output current gives it maximum design flexibility. The supply voltage should be maintained at 5V for high efficiency. WITH CLEAR AND PRESET; WITH DUAL OUTPUT ENABLE; WITH READ-BACK are other characteristics of it.
