CD74HC688M Overview
Tube's materials are used for the packaging.Low package costs make the 20-SOIC (0.295, 7.50mm Width) well known in the electronic industry.This electronic part is designed with 8 Bits.74HC Series provides excellent value for its performance-cost ratio.There is an electronic part mounted in the way of Surface Mount.The output of this electrical device is Active Low. Providing 2V~6V Supply Voltage is necessary to ensure the device's normal functioning.For reliability, the Operating Temperature is -55°C~125°C.For standard grade applications, the Identity Comparator Type is suitable.Its High/Low output current allows for maximum design flexibility.There are 20 terminations, which are the practice of ending a transmission line with a device that matches the characteristic impedance of the line.The unit has 1 functions.It is possible to find its related parts based on its Base Part Number.Power is provided by a supply voltage of 4.5V.There is a 20 Pin Count on it.Computers and other communications devices have 20 pins, which are pronged contacts.Mounting of this electronic component is in the direction of Surface Mount.Comparator is a member of the HC/UH family of electronic devices.Arithmetic Circuit has it under its Subcategory.2/6V Power Supplies are used to power it.The maximal Supply Voltage (Vsup) reaches 6V.There should be more supply voltage (Vsup) than 2V.As an example, CASCADABLE is among the additions.Its maximum current is 8μA.An external factor does not affect how much quiescent current it consumes.Featuring maximum design flexibility, 20mA features an output current of 50 mA.Comparator is a highly versatile device since Comparator can operate wComparatorh a voltage of 8μA.
