CD74HC688E Overview
Tube's materials are used for the packaging.Electronic manufacturers are well aware of the 20-DIP (0.300, 7.62mm) because of its low package cost.An electronic part designed with 8 Bits is used in this product.A great value because of its performance-cost ratio, the 74HC Series has a lot to offer.Electronic part Through Hole is mounted here.The output of this electrical device is Active Low. Devices are provided with a 2V~6V Supply Voltage to ensure normal operation.To ensure its reliability, it operates at Operating Temperature -55°C~125°C.Application grade Identity Comparator Types are available.The High/Low output current of 5.2mA 5.2mA makes it capable of securing maximum design flexibility.In 20 terminations, the transmission line is terminated with a device whose characteristic impedance matches the transmission line's.There are 1 functions on it.Comparator is powered from a Supply Voltage of 5V.Electronic devices belonging to the HC/UH family make up this device.A maximum voltage supply (Vsup) is reached at 6V.A supply voltage (Vsup) greater than 2V is required.As an example, CASCADABLE is among the additions.
