The ’BCT8240A scan test devices with octal  
buffers 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 via the 4-wire  
test access port (TAP) interface.  
NC – No internal connection  
In the normal mode, these devices are functionally equivalent to the ’F240 and ’BCT240 octal buffers. 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 buffers.  
In the test mode, the normal operation of the SCOPE octal buffers 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.  
SCOPE is a trademark of Texas Instruments Incorporated.

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.  
PRODUCTION DATA information is current as of publication date.  
Products conform to specifications per the terms of Texas Instruments  
standard warranty. Production processing does not necessarily include  
testing of all parameters.
