2OE  
The  
SN74ALVCHR16245  
is  
designed  
for  
asynchronous communication between data buses.  
The control-function implementation minimizes  
external timing requirements.  
This device can be used as two 8-bit transceivers or  
one 16-bit transceiver. It allows data transmission  
from the A bus to the B bus or from the B bus to the  
A
bus, depending on the logic level at the  
direction-control (DIR) input. The output-enable (OE)  
input can be used to disable the device so that the  
buses are effectively isolated.  
All outputs, which are designed to sink up to 12 mA, include equivalent 26-Ω series resistors to reduce overshoot  
and undershoot.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.
