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.

(1) Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at  
www.ti.com/sc/package.  
(2) DBV/DCK/DRL: The actual top-side marking has one additional character that designates the assembly/test site.  
YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following  
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, = Pb-free).
