SN74ALS688DWRG4 Product Details

SN74ALS688DWRG4 Overview


Tape and Reel's materials went into the packaging.There is no doubt that the SOIC is well known in the electronic industry due to its low package cost.Electronic parts using 8 Bits are designed here.There is a 20 programming language for terminating.The unit has 1 functions.Power is supplied by the supply voltage 5V.This device has a 20 Pin Count.The pronged contacts on computers and other communications devices are called 20 pins.There is a mounting direction of Surface Mount on this electronic part.The electronic device in question is part of the ALS family.Located under Arithmetic Circuits, it is in the Subcategory.In order to run it, it needs a 5V power supply.For instance, CASCADABLE was added.This device operates at maximum current 19mA.Supply voltage should be kept at 5V.Therefore, in order to provide maximum reliability, it operates at 0 degrees Celsius.Comparator should result in a warmer temperature than 0°C.This device supports the maximum supply voltage for 5.5V.4.5V is the minimum supply voltage required for the system to operate.Set -2.6mA as the high-level output current.There is a low level output current set to 24mA.IDENTITY COMPARATOR logic IC is used.
