SN74ALS21ADR Overview
Packed in 14-SOIC (0.154, 3.90mm Width), the part is convenient for shipping overseas. This high-reliability packaging method uses advanced packaging methods Tape & Reel (TR). As a result, it works on the principle of AND Gate. This part needs a voltage of 4.5V~5.5V to function properly. Increasing operating temperature to around 0°C~70°C. In Surface Mount, the part is mounted. In the low and high states of output current, the current is 400μA 8mA. This item is from the 74ALS series. In total, there have been 14 terminations. There are 2 functions that significantly improve the user experience. It is part of the ALS family of chips. Using the 74ALS21 search parameter will show you device variants. Into the part body are injected 14 pins. There are many applications for this logic device, mounted at Surface Mount. The functions of 14 pins can be found in the datasheets. 4 inputs are supported by the part. In the quiescent state, the part has 1.4mA current flowing through it. In this logic device, the value is Gates. In this part, the load capacitance is 50pF. There is a method TR in it that is designed for the industry. This part requires 5V power supplies, according to its datasheet. In this case, the output current is rated as 8mA. Device contains 1 outputs. The operation uses 2 elements in total. There is a specification for the operating voltage of the chip, 5VV, which is referred to as the supply voltage.
