description/ordering information  
This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC8T245  
is optimized to operate with V /V set at 1.4 V to 3.6 V. It is operational with V /V as low as 1.2 V.  
CCA CCB  
CCA CCA  
CCA CCB  
The A port is designed to track V  
. V  
accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed  
to track V  
. V  
accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage  
bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
