The ’LVT16646 devices are 16-bit bus  
transceivers and registers designed for  
low-voltage (3.3-V) V  
operation, but with the  
CC  
capability to provide a TTL interface to a 5-V  
system environment.  
These devices can be used as two 8-bit transceivers or one 16-bit transceiver. 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 LVT16646 devices.
