The ’ABT8952 scan test devices with octal  
registered bus transceivers are members of the  
Texas Instruments SCOPE testability integra-  
ted-circuit family. This family of devices supports  
IEEE Standard 1149.1-1990 boundary scan to  
facilitate testing of complex circuit-board assem-  
blies. 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 ’BCT2952 and ’ABT2952 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.  
UNLESS OTHERWISE NOTED this document contains PRODUCTION  
DATA information 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.
