74AC521SC Overview

Packaging made from Tube's materials.20-SOIC (0.295, 7.50mm Width) is well known for its low package costs in the electronics industry.8 Bits are used in the design of this electronic part.Its performance-cost ratio makes the 74AC Series an excellent value.Located in Surface Mount is this electronic part.A Active Low value is output by this electrical device.To ensure proper functioning, a 2V~6V Supply Voltage is provided.Reliability is ensured by using the Operating Temperature of -40°C~85°C.The Identity Comparator Type qualifies for standard grade applications.As the output current of 24mA 24mA is high/low, it has maximum design flexibility.The related parts can be found based on the Base Part Number.During the signal interface of a computer or other device, there can be 20 pins, which are pronged contacts.A Surface Mount-axis mount is used for this electronic part.An external factor does not affect how much quiescent current it consumes.As its Supplier Device Package, it uses 20-SOIC.In order to guarantee reliability, it operates at 85°C, the maximum Operating Temperature.A warmer temperature than -40°C should be reached when it is operating.6V supports its maximum supply voltage.With a 2V supply voltage of minimum, it operates.Set 24mA as the high-level output current.Comparator is set to 24mA for the low level output current.The transmission of data takes place over 8 channels.
