This dual-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.

DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.
DCU: 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).
