† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings can be exceeded if the input and output clamp-current ratings are observed.
             2. This current only flows when the output is in the high state and V_O > V_CC.
             3. The package thermal impedance is calculated in accordance with JESD51.


Description

The 'LVTH18512 and 'LVTH182512 scan test devices with 18-bit universal bus transceivers are members of the Texas Instruments SCOPEE^TM testability integrated-circuit family. 'LVTH18512 and 'LVTH182512 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, 'LVTH18512 and 'LVTH182512 are designed specifically for low-voltage (3.3-V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.
