M74HC688B1R Overview
Using materials from Tube, the packaging is made.Because of its low package cost, the 20-DIP (0.300, 7.62mm) is well known in the electronic industry.An electronic part designed with 8 Bits is used in this product.The 74HC Series offers an excellent price-performance ratio.Through Hole is used to mount this electronic part.An electrical device of this type produces Active Low as an output.This device is equipped with a 2V~6V Supply Voltage so it can operate normally.Reliability is ensured by using the Operating Temperature of -55°C~125°C.For standard grade applications, the Identity Comparator Type is suitable.As the output current of 5.2mA 5.2mA is high/low, it has maximum design flexibility.The 20 command is used to program terminations.1 functions are available on it.Comparator can be established which parts are related to a Base Part Number.Comparator is powered from a Supply Voltage of 4.5V.The 20 Pin Count feature is included.There are 20 pins, which are pronged contacts as part of a signal interface in a computer or other communications device. There is a mounting direction of Through Hole on this electronic part.Electronic devices belonging to the HC/UH family make up this device.Subcategory Arithmetic Circuits contains it.In order to run it, it needs a 2/6V power supply.At 6V, the supply voltage reaches its maximum value (Vsup).There should be a difference between Vsup and 2V in the supply voltage.In addition to CASCADABLE, for example, other additions have been made.Despite external factors, it consumes 4μA of quiescent current.
