SN74HC688DW Product Details

SN74HC688DW Overview


Packaging made from Tube's materials.Electronic manufacturers are well aware of the 20-SOIC (0.295, 7.50mm Width) because of its low package cost.This electronic part is designed with 8 Bits.A great value because of its performance-cost ratio, the 74HC Series has a lot to offer.Located in Surface Mount is this electronic part.There is an output Active Low for this electrical device.To ensure proper functioning, a 2V~6V Supply Voltage is provided.To ensure reliability, it operates at -40°C~85°C Operating Temperature.There is no minimum grade requirement for the Identity Comparator Type.As the output current of 5.2mA 5.2mA is high/low, it has maximum design flexibility.20 is used for terminating programs.1 functions are available on it.Comparator is possible to establish Comparators related parts using the Base Part Number.Power is provided by a supply voltage of 5V.This device has 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. Mounting of this electronic component is in the direction of Surface Mount.The electronic device in question is part of the HC/UH family.Comparator can be found under the Arithmetic Circuit Subcategory.2/6V Power Supplies provide power to the device.As Supply Voltage (Vsup) reaches 6V, it is maximal.Comparator is recommended that the supply voltage (Vsup) be greater than 2V.The additions include CASCADABLE, for example.During operation, it will supply no more than 80μA watts of current.At 5V, the supply voltage should be maintained.External factors do not affect its ability to consume 8μA of quiescent current.With its high output current, 5.2mA offers maximum design flexibility.
