CD74HC688E Overview


Tube's packaging is made of Tube's materials.The 20-DIP (0.300, 7.62mm) is well known in the electronics industry for its low package cost.The electronic part in this photo is designed using 8 Bits.The 74HC Series offers an excellent price-performance ratio.Mounted in the middle of Through Hole is this electronic part.There is a Active Low output from this electrical device.There is a 2V~6V Supply Voltage present in order to ensure normal device operation.Reliability is ensured by using the Operating Temperature of -55°C~125°C.Identity Comparator Types can be used for standard-grade applications.High/Low output currents of the 5.2mA 5.2mA make it the most flexible board for design.The 20 command is used to program terminations.A 1 Function is included.It is possible to find its related parts based on its Base Part Number.4.5V is the supply voltage.The device is equipped with a 20 Pin Count.There are 20 pins, which are pronged contacts as part of a signal interface in a computer or other communications device. The electronic part is mounted in the direction of Through Hole.HC/UH devices are electronic devices.In the Subcategory of Arithmetic Circuits, it can be found.In order to run it, it needs a 2/6V power supply.Supply Voltage (Vsup) reaches maximal values at 6V.2V must be greater than Vsup.CASCADABLE, for instance, is included in the additions.There is a maximum current supply of 8μA for its operation.Without being affected by external factors, 8μA of quiescent current is consumed.Due to its ability to operate with a supply voltage of 8μA, it is very versatile.
