The ’ACT8997 are members of the Texas Instruments SCOPE™ testability integratedcircuit family.
This family of components facilitates testing of complex circuit-board assemblies.
The ’ACT8997 enhance the scan capability of TI’s SCOPE™ family by allowing augmentation of a system’s primary scan path with secondary scan paths (SSPs), which can be individually selected by the ’ACT8997 for inclusion in the primary scan path.
