description
These bus transceivers and registers are
designed specifically for low-voltage (3.3-V) V_CC
operation, but with the capability to provide a TTL
interface to a 5-V system environment.

The ’LVTH652 devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for
multiplexed transmission of data directly from the data bus or from the internal storage registers.
Output-enable (OEAB and OEBA) inputs are provided to control the transceiver functions. Select-control (SAB
and SBA) inputs are provided to select whether real-time or stored data is transferred. The circuitry used for
select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between
real-time and stored data. A low input selects real-time data and a high input selects stored data. Figure 1
illustrates the four fundamental bus-management functions that can be performed with the ’LVTH652 devices.
