SN74LS20DR Overview
Due to its 14-SOIC (0.154, 3.90mm Width) packaging, the part is convenient for international shipping. High reliability is ensured by the advanced packaging method Tape & Reel (TR). It works based on the NAND Gate logic principle. To ensure the part's full function, a voltage of 4.75V~5.25V is needed. Extended operating temperature around 0°C~70°C. The part is mounted in Surface Mount. In both high and low states, output current is 400μA 8mA. The number 74LS refers to it. In total, there have been 14 terminations. In addition to 2 functions that significantly boost the user experience, the part includes 2 other features. There is a chip like this in LS. Using the 74LS20 search parameter will show you device variants. An injection of 14 pins is performed into the body of the part. There are many applications for this logic device, mounted at Surface Mount. You can find the functions of the 14 pins in the datasheets. As of 4, the part supports 4 inputs. Parts in quiescent state carry 1.2mA current. The logic device in this example is a typical Gates. It includes the industry TR method. According to the datasheets, the part requires 5V power supplies. 8mA is the output current of the device. Device contains 1 outputs. During operation, there are 2 elements. Typical operating voltages for the chip are specified as being z volts when it is first manufactured. Standby mode has a maximum current of 800μA.
