SN74ALS666DWE4 Overview


In the 24-SOIC (0.295, 7.50mm Width) package, it is embedded. Tube is the way it is packaged. In this configuration, the output is set to Tri-State. This electrical device has Logic type D-Type Transparent Latch. Mounting this electronic component follows the Surface Mount method. A 4.5V~5.5V voltage supply is required for operation. It is 0°C~70°C at the operating temperature. It is a type of FPGA belonging to the 74ALS series. An electronic part with 8 bits is designed. This device has been designed with 24 terminations available. There is no doubt that it belongs to the family 74ALS666. In order to operate it, the supply voltage must be 5V. 24 pins are included. ALS is the family of this electronic device. The pin configuration of the device is 24. The electronic part is mounted in a way that corresponds to Surface Mount. This device has a total of 2 ports. The part belongs to the FF/Latches subcategory. A total of 5V power supplies are needed to run it. It contains 8 input lines where electronic circuits are present. Its 24mA output current allows for maximum design flexibility. A high level of efficiency is achieved by maintaining the supply voltage at 5V. It also has characteristics of WITH CLEAR AND PRESET; WITH DUAL OUTPUT ENABLE; WITH READ-BACK.
