The ’ABT18640 scan test devices with 18-bit  
inverting bus transceivers 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.  
TCK  
In the normal mode, these devices are 18-bit inverting bus transceivers. They can be used either as two 9-bit  
transceivers or one 18-bit transceiver. 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 the normal mode does not affect the functional operation of the SCOPE bus transceivers.  
Data flow is controlled by the direction-control (DIR) and output-enable (OE) inputs. Data transmission is  
allowed from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at DIR. OE can  
be used to disable the device so that the buses are effectively isolated.  
In the test mode, the normal operation of the SCOPE 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 according to the protocol 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.
