Application Notes
- Understanding Buffered and Unbuffered CD4xxxB Series Device CharacteristicsPDF, 188 Kb, File published: Dec 3, 2001
Both buffered and unbuffered CMOS B-series gates inverters and high-current IC products are available from TI. Each product classification has application advantages in appropriate logic-system designs. Many CMOS suppliers have concentrated on promoting buffered B-series products with applications literature focusing on the attributes and use of the buffered types. This practice has left an imb
