74HCT688D,653 Product Details
74HCT688D,653 Overview
Materials from Tape & Reel (TR) are used to make the packaging.Electronic manufacturers are well aware of the 20-SOIC (0.295, 7.50mm Width) because of its low package cost.8 Bits are used in the design of this electronic part.The 74HCT Series offers an excellent price-performance ratio.Mounted in the way of Surface Mount, this electronic part is mounted in the way of X.A Active Low value is output by this electrical device.An internal 4.5V~5.5V Supply Voltage ensures the device's normal operation.Reliability is ensured by using the Operating Temperature of -40°C~125°C.There is no minimum grade requirement for the Identity Comparator Type.The High/Low output current of 4mA 4mA makes it capable of securing maximum design flexibility.Termination with a 20 device, which matches the transmission line's characteristic impedance, is considered a 20 termination.There are 1 functions on it.Parts related to the Base Part Number can be derived from it.Supply Voltage 5V powers the device.A total of 20 pins are equipped with it.There is an electronic device in this family called HCT.Comparator is located in Arithmetic Circuits Subcategory.5V Power Supplies are used to power it.Upon reaching 5.5V, the maximal supply voltage (Vsup) is reached.4.5V must be greater than Vsup.For instance, CASCADABLE was added.
