DESCRIPTION
The 74ABT652A high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT652A transceiver/register consists of bus transceiver
circuits with 3-State outputs, D-type flip-flops, and control circuitry
arranged for multiplexed transmission of data directly from the input
bus or the internal registers. Data on the A or B bus will be clocked
into the registers as the appropriate clock pin goes High. Output
Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for
bus management.

Low-to-High clock transition
The data output function may be enabled or disabled by various signals at the OEBA and OEAB inputs. Data input functions are always
enabled, i.e., data at the bus pins will be stored on every Low-to-High transition of the clock.
If both Select controls (SAB and SBA) are Low, then clocks can occur simultaneously. If either Select control is High, the clocks must be
staggered in order to load both registers.
