SN74ABTH182646APM Descrizione

***as Instruments: Scan Test Devices With 18-Bit Transceivers And egisters 64-LQFP -40 to 85

***ical: Scan Test Device -40C to 85C 64-Pin LQFP Tray

***et: Bus XCVR Dual 18-CH 3-ST 64-Pin LQFP Tray

***INS: The 'ABTH18646A and 'ABTH182646A scan test devices with 18-bit bus transceivers and registers are members 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.

***AS INSRUMENTS: In the normal mode, these devices are 18-bit bus transceivers and registers that allow for multiplexed transmission of data directly from the input bus or from the internal registers. They 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. Activating the TAP in the normal mode does not affect the functional operation of the SCOPETM bus transceivers and registers.

***as Instruments Inc.: Transceiver function is controlled by output-enable () and direction (DIR) inputs. When is low, the transceiver is active and operates in the A-to-B direction when DIR is high or in the B-to-A direction when DIR is low. When is high, both the A and B outputs are in the high-impedance state, effectively isolating both buses.

***AS INSTUMENTS: Data flow is controlled by clock (CLKAB and CLKBA) and select (SAB and SBA) inputs. Data on the A bus is clocked into the associated registers on the low-to-high transition of CLKAB. When SAB is low, real-time A data is selected for presentation to the B bus (transparent mode). When SAB is high, stored A data is selected for presentation to the B bus (registered mode). The function of the CLKBA and SBA inputs mirrors that of CLKAB and SAB, respectively. Figure 1 shows the four fundamental bus-management functions that are performed with the 'ABTH18646A and 'ABTH182646A.

***AS INSTRU

***: In the test mode, the normal operation of the SCOPETM bus transceivers and registers is inhibited, and the test circuitry is enabled to observe and control the I/O boundary of the device. When enabled, the test circuitry performs boundary-scan test operations according to the protocol described in IEEE Standard 1149.1-1990.

***AS INSTR: Four dedicated test pins observe and 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.

***: Improved scan efficiency is accomplished through the adoption of a one boundary-scan cell (BSC) per I/O pin architecture. This architecture is implemented in such a way as to capture the most pertinent test data. A PSA/COUNT instruction also is included to ease the testing of memories and other circuits where a binary count addressing scheme is useful.

***AS INST: Active bus-hold circuitry holds unused or floating data inputs at a valid logic level.

***AS INSTRU: The B-port outputs of 'ABTH182646A, which are designed to source or sink up to 12 mA, include 25- series resistors to reduce overshoot and undershoot.

***XS: The SN54ABTH18646A and SN54ABTH182646A are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABTH18646A and SN74ABTH182646A are characterized for operation from -40°C to 85°C.

***ASI

***TEXAS

***as Instr.: The data-output functions can be enabled or disabled by various signals at and DIR. Data-input functions are always enabled; i.e., data at the bus pins is stored on every low-to-high transition of the clock inputs.
