SN74LVTH18512DGGR 描述

***as Instruments: 3.3-V ABT Scan Test Devices With 18-Bit Universal Bus Transceivers 64-TSSOP -40 to 85

***et: Bus XCVR Dual 18-CH 3-ST 64-Pin TSSOP T/R

***Components: 74LVTH18512DGGR 18-bit transceiver,TSSOP

***i-Key: IC SCAN TEST UNIV TXRX 64TSSOP

***AS INSRUMENT: The 'LVTH18512 and 'LVTH182512 scan test devices with 18-bit universal bus transceivers are members of the Texas Instruments SCOPETM testability integrated-circuit family. This family of devices supports IEEE Std 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 Instr.: Additionally, these devices are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

***INS: In the normal mode, these devices are 18-bit universal bus transceivers that combine D-type latches and D-type flip-flops to allow data flow in transparent, latched, or clocked modes. 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 universal bus transceivers.

***AS INSRUMENT: Data flow in each direction is controlled by output-enable (OEAB\ and OEBA\), latch-enable (LEAB and LEBA), and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the devices operate in the transparent mode when LEAB is high. When LEAB is low, the A data is latched while CLKAB is held at a static low or high logic level. Otherwise, if LEAB is low, A data is stored on a low-to-high transition of CLKAB. When OEAB\ is low, the B outputs are active. When OEAB\ is high, the B outputs are in the high-impedance state. B-to-A data flow is similar to A-to-B data flow but uses the OEBA\, LEBA, and CLKBA inputs.

***as Instr.: In the test mode, the normal operation of the SCOPETM universal bus transceivers 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 Std 1149.1-1990.

***XS: Four dedicated test pins are used to 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.

***AS INSTRUM: Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

***TEXAS: The B-port outputs of 'LVTH182512, which are designed to source or sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.

***AS INSTRUMENTS INC: The SN54LVTH18512 and SN54LVTH182512 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LVTH18512 and SN74LVTH182512 are characterized for operation from -40°C to 85°C.
