SN74ALS666DWR Overview


The package in which it is embedded is named 24-SOIC (0.295, 7.50mm Width). Tape & Reel (TR) is the packaging method. It uses the output configuration Tri-State. There is D-Type Transparent Latch logic type for this electrical device. Mounting this electronic component follows the Surface Mount method. A 4.5V~5.5V voltage supply is required for operation. There is 0°C~70°C operating temperature. There are a number of FPGAs in this series, including this one. The design of this electronic part contains 8 bits. There are 24 terminations, which are the practice of ending a transmission line with a device that matches the characteristic impedance of the line. There is no doubt that it belongs to the family 74ALS666. The device works with a voltage of 5V for its supply voltage. 24 pins are provided. ALS is the family name of this electronic device. In addition, it is designed with a pin number of 24. The electronic part is mounted using the Surface Mount method. As far as ports are concerned, this device has 2 ports. It belongs to the subcategory of FF/Latches. The system is powered by 5V sources. It contains 8 input lines where electronic circuits are present. Its reliable performance makes it an excellent choice for TAPE AND REEL. Its output current of 24mA ensures maximum design flexibility. A high level of efficiency is achieved by maintaining the supply voltage at 5V. There are also other characteristics of it, such as WITH CLEAR AND PRESET; WITH DUAL OUTPUT ENABLE; WITH READ-BACK.
