description
The ’LVT16646 are 16-bit bus transceivers designed for low-voltage (3.3-V) V
CC
operation, but with the
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.
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 circuitry
used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition
between stored and real-time 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.
