74LVTH646  
Low Voltage Octal Transceiver/Register  
with 3-STATE Outputs  
General Description  
Features  
Input and output interface capability to systems at  
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)  
5V VCC  
Bushold data inputs eliminate the need for external  
pull-up resistors to hold unused inputs  
Live insertion/extraction permitted  
Power Up/Down high impedance provides glitch-free  
bus loading  
The LVTH646 data inputs include bushold, eliminating the  
need for external pull-up resistors to hold unused inputs.  
Outputs source/sink 32 mA/+64 mA  
Functionally compatible with the 74 series 646  
Latch-up performance exceeds 500 mA  
The bus transceivers are designed for low-voltage (3.3V)  
VCC 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.
