operation, but with the capability to provide a TTL  
interface to a 5-V system environment.  
NC – No internal connection  
The ’LVT646 consist of bus transceiver circuits,  
D-type flip-flops, and control circuitry arranged for  
multiplexed transmission of data directly from the  
input bus or from the internal registers. Data on the A or B bus is clocked into the registers on the low-to-high  
transition of the appropriate clock (CLKAB or CLKBA) input. Figure 1 illustrates the four fundamental  
bus-management functions that can be performed with the ′LVT646.  
Output-enable (OE) and direction-control (DIR) inputs are provided to control the transceiver functions. In the  
transceiver mode, data present at the high-impedance port may be stored in either register or in both.  
The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode) data. The  
direction control (DIR) determines which bus receives data when OE is low. In the isolation mode (OE high),  
A data may be stored in one register and/or B data may be stored in the other register.  
When an output function is disabled, the input function is still enabled and may be used to store and transmit  
data. Only one of the two buses, A or B, may be driven at a time.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
