SN74ALS990DWR Overview


The 20-SOIC (0.295, 7.50mm Width) package contains it. A package of Tape & Reel (TR) has been used. There is a Tri-State output configured. This electrical device has a logic type of D-Type Transparent Latch. The way in which this electronic part is mounted is Surface Mount. A 4.5V~5.5V supply voltage is required to operate it. A temperature of 0°C~70°C is used for operation. In the 74ALS series, this FPGA is located. An electronic part with 8 bits is designed. The device consists of 20 terminations that are designed to be used in conjunction with it. There is no doubt that it belongs to the family 74ALS990. The device works with a voltage of 5V for its supply voltage. The 20 pind are equipped with it. In the world of electronics, this electronic device belongs to the family of ALS. This board has 20 pins on it, which is what it is designed for. Mounting this electronic component follows the Surface Mount method. The part belongs to the FF/Latches subcategory. There is 5V power supply for it. It consists of 8 input lines from which an electronic circuit can be built. The device's reliable performance makes it a good choice for TR. The output current of 24mA makes it feature maximum design flexibility. For maximum efficiency, the supply voltage should be set to 5V. There are also characteristics of WITH READ-BACK associated with it.
