1 / 31 page SN54ABT8652, SN74ABT8652 SCAN TEST DEVICES WITH OCTAL BUS TRANSCEIVERS AND REGISTERS SCBS122F – AUGUST 1992 – REVISED DECEMBER 1996 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Members of the Texas Instruments SCOPE ™ Family of Testability Products D Compatible With the IEEE Standard 1149.1-1990 (JTAG) Test Access Port and Boundary-Scan Architecture D Functionally Equivalent to ’F652 and ’ABT652 in the Normal-Function Mode D SCOPE ™ Instruction Set – IEEE Standard 1149.1-1990 Required Instructions, Optional INTEST, CLAMP, and HIGHZ – Parallel-Signature Analysis at Inputs With Masking Option – Pseudo-Random Pattern Generation From Outputs – Sample Inputs/Toggle Outputs – Binary Count From Outputs – Even-Parity Opcodes D Two Boundary-Scan Cells Per I/O for Greater Flexibility D State-of-the-Art EPIC-ΙΙB ™ BiCMOS Design Significantly Reduces Power Dissipation D Package Options Include Shrink Small-Outline (DL) and Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Ceramic DIPs (JT) description The ’ABT8652 scan test devices with octal bus transceivers and registers 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. In the normal mode, these devices are functionally equivalent to the ’F652 and ’ABT652 octal bus transceivers and registers. 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 bus transceivers and registers.
