Description

The 'ACT8997 are members of the Texas Instruments SCOPE^TM testability integrated-circuit family. This family of components facilitates testing of complex circuit-board assemblies.

The 'ACT8997 enhance the scan capability of TI's SCOPE^TM 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. These devices also provide buffering of test signals to reduce the need for external logic.

By loading the proper values into the instruction register and data registers, the user can select up to four SSPs to be included in a primary scan path. Any combination of the SSPs can be selected at a time.
