The ’LVTH18652A and ’LVTH182652A scan test devices with 18-bit bus transceivers and registers are members of the Texas Instruments (TI) SCOPE testability integrated-circuit family.
This family of devices supports IEEE Std 1149.1-1990 boundary scan to facilitate testing of plex circuit board assemblies.
Scan access to the test circuitry is acplished via the 4-wire test access port (TAP) interface.
