description/ordering information  
This dual-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is  
designed to track V . V accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track  
CCA CCA  
V
. V  
accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional  
CCB CCB  
translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.  
The SN74LVC2T45 is designed for asynchronous communication between data buses. The device transmits  
data 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.
