MM74HC688WMX Overview
Packaging made from Tape & Reel (TR)'s materials.20-SOIC (0.295, 7.50mm Width) is well known for its low package costs in the electronics industry.Using 8 Bits, this electronic component was designed.Performance-cost ratio makes the 74HC Series a great value.There is a Surface Mount-position for this electronic part.The output of this electrical device is Active Low. 2V~6V Supply Voltage provides the device with the necessary stability.Comparator operates wComparatorh the Operating Temperature of -40°C~85°C to ensure Comparators reliabilComparatory.The Identity Comparator Type qualifies for standard grade applications.As 5.2mA 5.2mA features a high/low output current, maximal design flexibility can be achieved.An example of a 20 termination would be one in which the characteristic impedance of the transmission line is matched to the device terminating the transmission line.A 1 Function is included.Power comes from a supply voltage of 4.5V.20 Pin Count is equipped with it.This electronic device belongs to the family of HC/UH.Supply Voltage (Vsup) reaches maximal values at 6V.There should be a higher voltage supply (Vsup) than 2V.CASCADABLE, for instance, is included in the additions.
