† _{Component qualification in accordance with JEDEC and industry}
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

description/ordering information
This bus transceiver and register is 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 SN74LVTH652 consists 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 SN74LVTH652
device.
