74LVTH16646  
Low Voltage 16-Bit Transceiver/Register  
with 3-STATE Outputs  
General Description  
Features  
Input and output interface capability to systems at  
The LVTH16646 contains sixteen non-inverting bidirec-  
tional registered bus transceivers providing multiplexed  
transmission of data directly from the input bus or from the  
internal storage registers. Each byte has separate control  
inputs which can be shorted together for full 16-bit opera-  
tion. The DIR inputs determine the direction of data flow  
through the device. The CPAB and CPBA inputs load data  
into the registers on the LOW-to-HIGH transition (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  
Outputs source/sink 32 mA/+64 mA  
The LVTH16646 data inputs include bushold, eliminating  
the need for external pull-up resistors to hold unused  
inputs.  
Functionally compatible with the 74 series 16646  
Latch-up performance exceeds 500 mA  
These transceivers are designed for low-voltage (3.3V)  
VCC applications, but with the capability to provide a TTL  
interface to a 5V environment. The LVTH16646 is fabri-  
cated with an advanced BiCMOS technology to achieve  
high speed operation similar to 5V ABT while maintaining  
low power dissipation.
