DESCRIPTION/ORDERING INFORMATION  
The 'LVT162245A devices are 16-bit (dual-octal) noninverting 3-state transceivers designed for low-voltage  
(3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.  
These devices are designed for asynchronous communication between two data buses. The logic levels of the  
direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port  
outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to  
the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are  
activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level  
applied to prevent excess ICC and ICCZ  
.
The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-series resistors  
to reduce overshoot and undershoot.  
When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.  
However, to ensure the high-impedance state above 1.5 V, 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.  
These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry  
disables the outputs, preventing damaging current backflow through the devices when they are powered down.  
The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.
