The ’ABTH18652A and ’ABTH182652A scan test devices with 18-bit bus transceivers and registers are members of the Texas Instruments SCOPE testability integrated-circuit family. This family of devices supports IEEE Standard 1149.1-1990 boundary scan to facilitate testing of complex circuit-board assemblies. Scan access to the test circuitry is accomplished vi.
