SN74AS21D Overview


The part comes in 14-SOIC (0.154, 3.90mm Width) packaging, which makes it convenient to ship overseas. In order to provide high reliability, an advanced packaging method Tube is used. Based on the AND Gate logic principle, it works. A voltage of 4.5V~5.5V is needed to ensure full function of the part. Temperatures around 0°C~70°C are extended for operation. Part Surface Mount is mounted. In both high and low states, output current is 2mA 20mA. The number 74AS refers to it. In total, there are 14 terminations. User experience is significantly enhanced by the part's 2 functions. I would like to point out that this chip is part of AS. Search with 74AS21 if you are looking for device variants. Part bodies are injected with 14 pins. Surface Mount mounted, this logic device is widely used in many applications. Please refer to the datasheets for 14 pins functions. It supports inputs of 4. There is a standard Gates logic device here. 50pF is the load capacitance of the part. This part requires 5V power supplies, according to its datasheet. Its output current is rated at 20mA. The device has 1 outputs. The operation uses 2 elements in total. In the specification of the chip, it is specified that the operating supply voltage will be 5V volts.
