10-BIT ADDRESSABLE SCAN PORTS MULTIDROP-ADDRESSABLE IEEE STD 1149.1 JTAG TAP TRANSCEIVERS

The ABT8996 10-bit addressable scan ports (ASP) are members of the Texas Instruments (TI) SCOPE testability integrated-circuit family. This family of devices supports IEEE Standard 1149.1-1990 boundary scan to facilitate testing of complex circuit assemblies. Unlike most SCOPE devices, the ASP is not a boundary-scannable device, rather, it applies TIs addressable-shadow-port technology to the IEEE Standard 1149.1-1990 (JTAG) test access port (TAP) to extend scan access beyond the board level. Conceptually, the ASP is a simple Switch that CAN be used to directly connect a set of multidrop primary TAP signals to a set of secondary TAP signals for example, to Interface Backplane TAP signals to a board-level TAP. The ASP provides all signal buffering that might be required at these two Interfaces When primary and secondary TAPs are connected, only a moderate propagation delay is introduced no storage/retiming elements are inserted. This minimizes the need for reformatting board-level test vectors for in-system use. By Texas Instruments
