DESCRIPTION/ORDERING INFORMATION  
This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. 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-V voltage nodes.
