description/ordering information
This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is
designed to track V
CCA
. V
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.
The SN74AVCH1T45 is designed for asynchronous communication between data buses. The device transmits
data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the
direction-control (DIR) input.
The SN74AVCH1T45 is designed so that the DIR input is powered by V
CCA
.

DBV/DCK: 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).
