The ’ABT8543 scan test devices with octal  
registered bus transceivers are members of the  
1213 14 15 16 17 18  
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.  
In the normal mode, these devices are functionally equivalent to the ’F543 and ’ABT543 octal registered bus  
transceivers. The test circuitry can be activated by the TAP to take snapshot samples of the data appearing at  
the device pins 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 registered bus transceivers.  
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 and EPIC-ΙΙB are trademarks of Texas Instruments Incorporated.  
Copyright 1996, 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.
