SN54ABT18646 具有 18 位总线收发器和寄存器的扫描测试设备

The SN54ABT18646 scan test device with 18-bit bus transceivers and registers is a member of the Texas Instruments SCOPETM 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, the SN54ABT18646 is an 18-bit bus transceiver and register that allows for multiplexed transmission of data directly from the input bus or from the internal registers. It 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
