SN74BCT8374A Overview
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 plex circuit-board assemblies. Scan access to the test circuitry is acplished via the 4-wire test access port (TAP) interface.
