74ACT521MTCX Overview
Packaging made from Tape & Reel (TR)'s materials.Electronic manufacturers are well aware of the 20-TSSOP (0.173, 4.40mm Width) because of its low package cost.A 8 Bit electronic part is used to design this part.74ACT Series offers excellent performance at an affordable price.Mounted in the way of Surface Mount, this electronic part is mounted in the way of X.In this case, Active Low is the electrical device's output.Devices need a 4.5V~5.5V Supply Voltage to function normally.For reliability, the Operating Temperature is -40°C~85°C.Comparator is suComparatorable for standard grade applications.The High/Low output current of 24mA 24mA makes it Feature maximum design flexibility.Based on the Base Part Number, related parts can be identified.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.5V should be maintained as the Supply Voltage.Comparator consumes 4μA of quiescent current wComparatorhout being affected by external factors. Supplier Device Package 20-TSSOP is employed by it.This device operates at its maximum Operating Temperature of 85°C in order to ensure its reliability.When it is operating, it should feel warmer than -40°C.Besides supporting the maximum supply voltage, it also supports the maximum power consumption.Using 4.5V as the minimum supply voltage, it operates.In this case, 24mA is the output current at the high level.Comparator is set to 24mA for the low level output current.
