八进制D类锁存器扫描测试设备 SCAN TEST DEVICES WITH OCTAL D-TYPE LATCHES

description

The ’BCT8373A scan test devices with octal D-type latches 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.
