description  
The SN74ALB16245 is a 16-bit transceiver  
designed for high-speed, low-voltage (3.3-V) V  
CC  
operation. This device is intended to replace the  
conventional transceiver in any speed-critical  
path. The small propagation delay is achieved  
using a unity-gain amplifier on the input and  
feedback resistors from input to output, which  
allows the output to track the input with a small  
offset voltage.

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  
theBbustotheAbus, dependingonthelogiclevel  
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.
