与八D型边沿触发触发器扫描测试设备 SCAN TEST DEVICES WITH OCTAL D-TYPE EDGE-TRIGGERED FLIP-FLOPS

description

The ’BCT8374A scan test devices with octal edge-triggered D-type flip-flops 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.
