SN74ALS990DW Overview
In the 20-SOIC (0.295, 7.50mm Width) package, it can be found as an embedded module. Packaged in the way of Tube. It uses Tri-State as the output. In this electrical device, the logic type is D-Type Transparent Latch. Based on the way of Surface Mount, this electronic part is mounted. There is no supply voltage for this device. A temperature of 0°C~70°C is set as the operating temperature. 74ALS is the series number of this FPGA. The design of this electronic part is based on 8 bits. A device such as this has 20 terminations designed. The family 74ALS990 includes it. The device works with a voltage of 5V for its supply voltage. There are 20 pins attached to it. It is part of the family of electronic devices called ALS. This board has 20 pins on it, which is what it is designed for. This electronic part is mounted in the way of Surface Mount. There is a subcategory of FF/Latches for this part. There are 5V power supplies required for this machine to operate. There are 8 input lines in which electronic circuits are present. With 24mA, maximum design flexibility is ensured. In order to achieve high efficiency, the supply voltage should be kept at 5V. The current consumed by the device is 40mA volts in quiescent mode, which cannot be affected by external factors. It also has characteristics of WITH READ-BACK.
