UNISONIC TECHNOLOGIES CO., LTD  
U74AVC2T45  
Preliminary  
CMOS IC  
DUAL-BIT DUAL SUPPLY, BUS  
TRANSCEIVER WITH  
CONFIGURABLE  
LEVEL-SHIFTING AND  
TRANSLATION  
SOP-8  
DESCRIPTION  
This 2-bit non-inverting bus transceiver uses two separate  
configurable power-supply rails. The A ports are designed to track  
VCCA and accepts any supply Voltage from 1.2V to 3.6V. The B  
ports are designed to track VCCB and accepts any supply Voltage  
from 1.2V to 3.6V. This allows for universal low Voltage  
bidirectional translation and level-shifting between any of the 1.2V,  
1.5V, 1.8V, 2.5V, and 3.3V Voltage nodes.  
The  
U74AVC2T45  
is  
designed  
for  
asynchronous  
communication between two data buses. The logic levels of the  
direction-control (DIR pin) input activate either the B-port outputs or  
the A-port outputs. The device transmits data from the A bus to the  
B bus when the B-port outputs are activated and from the B bus to  
the A bus when the A-port outputs are activated. The input circuitry  
on both A and B ports always is active and must have a logic HIGH  
or LOW level applied to prevent excess leakage current on the  
internal CMOS structure.  
FEATURES  
* VCC Isolation Feature: If Either VCC Input Is at GND, Both Ports  
Are in the High-Impedance State  
* Dual Supply Rail Design  
* I/Os Are 4.6V Over Voltage Tolerant  
* IOFF Supports Partial-Power-Down Mode Operation
