description  
B2  
The ’BCT8245A scan test devices with octal bus  
transceivers are members of the Texas  
12 13 14 15 16 17 18  
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 via the  
4-wire test access port (TAP) interface.  
NC – No internal connection  
In the normal mode, these devices are functionally equivalent to the ’F245 and ’BCT245 octal bus transceivers.  
The test circuitry can be activated by the TAP to take snapshot samples of the data appearing at the device  
terminals or to perform a self test on the boundary-test cells. Activating the TAP in normal mode does not affect  
the functional operation of the SCOPE octal bus transceivers.  
In the test mode, the normal operation of the SCOPE octal bus transceivers is inhibited and the test circuitry  
is enabled to observe and control the I/O boundary of the device. When enabled, the test circuitry can perform  
boundary-scan test operations as described in IEEE Standard 1149.1-1990.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

On products compliant to MIL-PRF-38535, all parameters are tested  
unless otherwise noted. On all other products, production  
processing does not necessarily include testing of all parameters.
