DESCRIPTION/ORDERING INFORMATION
This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The
SN74AVC1T45 is optimized to operate with V
/V
CCB
set at 1.4 V to 3.6 V. It is operational with V
/V
as
low as 1.2 V. The A port is designed to track V
CCA
CCA
accepts any supply voltage from 1.2 V to 3.6 V. The
B port is designed to track V
CCB
. V
CCB
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.

DBV/DCK/DRL: The actual top-side marking has one additional character that designates the assembly/test site.
YEP/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).
