DESCRIPTION/ORDERING INFORMATION  
This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.  
The SN74ALVCH16245-EP 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.
