Both leaded and nonleaded packages available with pin counts ranging from 5 to 20 pins. Wettable flanks available on select packages.
Schmitt-trigger inputs
Our new HCS family features Schmitt-trigger inputs allowing for superior noise immunity.
Common applications of OR gates
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.

Application note
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.
Application note
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.
Application note
User Fewer Inputs to Monitor Error Signals
Error source signals can be combined to reduce the number of required inputs to a system controller when it is more important to know that an error has occurred than it is to know which device triggered the error.
