description
The ’LVTH18514 and ’LVTH182514 scan test devices with 20-bit universal bus transceivers are members of
the TI SCOPE testability integrated-circuit family. This family of devices supports IEEE Std 1149.1-1990
boundary scan to facilitate testing of complex circuit-board assemblies. Scan access to the test circuitry is
accomplished via the 4-wire test access port (TAP) interface.
Additionally, these devices are designed specifically for low-voltage (3.3-V) VCC operation, but with the
capability to provide a TTL interface to a 5-V system environment.
