Common applications of D-type latches

Digital signals sometimes need to be enabled or disabled during system operation. This video explores all the options for what to do with the output when a line is disabled, and identifies logic devices that can perform each function.

Understanding Schmitt Triggers (Rev. A)
Most CMOS, BiCMOS and TTL devices require fairly fast edges on the high and low transitions on their inputs. If the edges are too slow they can cause excessive current, oscillation and even damage the device.

Optimizing Board Space for Discrete LOGIC Designs Using Smallest Package Solutio (Rev. A)
The term dual footprint here refers to overlaying two PCB landing pads for two different package configurations. In supply constrained environments, this is a great method to mitigate supply issues for new designs or board spins.

An Overview of Bus-Hold Circuit and the Applications (Rev. B)
When designing systems that include (CMOS) devices, designers must pay special attention to the operating condition in which all of the bus drivers are in an inactive, high-impedance condition (tri-state).
