5962-9172701QLA Descrizione generale

The 'BCT8374A scan test devices with octal edge-triggered D-type flip-flops are members of the Texas Instruments SCOPE^TM 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, these devices are functionally equivalent to the 'F374 and 'BCT374 octal D-type flip-flops. The test circuitry can be activated by the TAP to take snapshot samples of the data appearing at the device terminals or to perform a self test on the boundary-test cells. Activating the TAP in normal mode does not affect the functional operation of the SCOPE^TM octal flip-flops.

In the test mode, the normal operation of the SCOPE^TM octal flip-flops is inhibited and the test circuitry is enabled to observe and control the I/O boundary of the device. When enabled, the test circuitry can perform boundary-scan test operations as described in IEEE Standard 1149.1-1990.

Four dedicated test terminals control the operation of the test circuitry: test data input (TDI), test data output (TDO), test mode select (TMS), and test clock (TCK). Additionally, the test circuitry performs other testing functions such as parallel-signature analysis (PSA) on data inputs and pseudo-random pattern generation (PRPG) from data outputs. All testing and scan operations are synchronized to the TAP interface.

The SN54BCT8374A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74BCT8374A is characterized for operation from 0°C to 70°C.
