DESCRIPTION/ORDERING INFORMATION
SN74AVCH1T45
SINGLE-BIT DUAL-SUPPLY BUS TRANSCEIVER
WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS
SCES598C – JULY 2004 – REVISED OCTOBER 2005
Available in the Texas Instruments
NanoStar and NanoFree Packages
Control Inputs VIH/VIL Levels Are Referenced
to VCCA Voltage
Fully Configurable Dual-Rail Design Allows
Each Port to Operate Over the Full 1.2-V to
3.6-V Power-Supply Range
I/Os Are 4.6-V Tolerant
Ioff Supports Partial-Power-Down Mode

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 1.2 V to 3.6 V. The B port is designed to track
VCCB. VCCB 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 VCCA.

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).
