SN74HC688PWRE4 Product Details

SN74HC688PWRE4 Overview


Material from Tape & Reel (TR) is used in the packaging.20-TSSOP (0.173, 4.40mm Width) is well known for its low package costs in the electronics industry.8 Bits are used in the design of this electronic part.74HC Series provides excellent value for its performance-cost ratio.There is an electronic component mounted in the way of Surface Mount.Using this electrical device, Active Low is the output.Providing 2V~6V Supply Voltage is necessary to ensure the device's normal functioning.As a result, it operates with an Operating Temperature of -40°C~85°C, which ensures its reliability.For standard grade applications, the Identity Comparator Type is suitable.With the High/Low output current of 5.2mA 5.2mA, it features maximum design flexibility.A transmission line may also have 20 terminations, which are made using devices matched to its characteristic impedance.The 1-functions are included.The related parts can be found based on the Base Part Number.5V is the supply voltage.In addition, it features 20 Pin Count.An interface in a computer or other communication device has 20 pins, which are pronged contacts.In this case, the electronic part is mounted in the direction of Surface Mount.There is an electronic device in this family called HC/UH.You can find it under Arithmetic Circuits Subcategory.Powered by a 2/6V power supply, it runs on batteries.A maximum voltage supply (Vsup) is reached at 6V.Supply voltage (Vsup) should be greater than 2V.CASCADABLE, for example, is one of the additions.Ensure that 5V is the Supply Voltage.The device consumes 8μA quiescent current without being affected by external factors.This device performs well at TR.
