DESCRIPTION/ORDERING INFORMATION  
This 8-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74LVC8T245  
is optimized to operate with VCCA and VCCB set at 1.65 V to 5.5 V. The A port is designed to track VCCA. VCCA  
accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply  
voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the  
1.8-V, 2.5-V, 3.3-V, and 5.5-V voltage nodes.
