CD74HCT688E Overview
Material from Tube is used in the packaging.There is no doubt that the 20-DIP (0.300, 7.62mm) is well known for its low package cost in the electronic industry.Comparator is designed with 8 Bits.74HCT Series provides excellent value for its performance-cost ratio.Electronic part Through Hole is mounted here.This electrical device produces Active Low as its output.Devices need a 4.5V~5.5V Supply Voltage to function normally.In order to ensure its reliability, it operates at a temperature of -55°C~125°C.For standard grade applications, the Identity Comparator Type is suitable.As a result of the high/low output current feature, 4mA 4mA offers maximum design flexibility.20 controls terminations.In addition, it has 1 functions.Base Part Numbers can be used to identify related parts.A supply voltage of 5V is used to power it.This device has a 20 Pin Count.An interface in a computer or other communication device has 20 pins, which are pronged contacts.Mounted in the Through Hole direction is this electronic part.Electronic devices of this type are known as HCT devices.Comparator is located in Arithmetic Circuits Subcategory.Power is supplied by a 5V Power Supply.As an example, CASCADABLE is among the additions.In its operation, 80μA represents the maximum current.Maintain a voltage of 5V for the supply voltage.External factors do not affect its ability to consume 8μA of quiescent current.20mA has a high output current, which allows for maximum design flexibility.1-channels transmit data.
