74LVTH646
Low Voltage Octal Transceiver/Register
with 3-STATE Outputs
General Description
The LVTH646 consists of registered bus transceiver cir-
cuits, D-type flip-flops, and control circuitry providing multi-
plexed transmission of data directly from the input bus or
from the internal storage registers. Data on the A or B bus
will be loaded into the respective registers on the LOW-to-
HIGH transition of the appropriate clock pin (CPAB or
CPBA). (See Functional Description)
The LVTH646 data inputs include bushold, eliminating the
need for external pull-up resistors to hold unused inputs.
The bus transceivers are designed for low-voltage (3.3V)

applications, but with the capability to provide a TTL
interface to a 5V environment. The LVTH646 is fabricated
with an advanced BiCMOS technology to achieve high
speed operation similar to 5V ABT while maintaining low
power dissipation.
