FEATURES  
DESCRIPTION  
Qualified for Automotive Applications  
This 8-bit non-inverting bus transceiver uses two  
separate configurable power-supply rails. The  
SN74LVC8T245-Q1 is optimized to operate with VCCA  
and VCCB set at 1.65 V to 5.5 V. 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 5.5-V voltage nodes.  
Control Inputs VIH/VIL Levels Are Referenced to  
VCCA Voltage  
VCC Isolation Feature – If Either VCC Input Is at  
GND, All Are in the High-Impedance State  
Fully Configurable Dual-Rail Design Allows  
Each Port to Operate Over the Full 1.65-V to  
5.5-V Power-Supply Range  
PW PACKAGE  
(TOP VIEW)  
The  
SN74LVC8T245-Q1  
is  
designed  
for  
asynchronous communication between two data  
buses. The logic levels of the direction-control (DIR)  
input and the output-enable (OE) input activate either  
the B-port outputs or the A-port outputs or place both  
output ports into the high-impedance mode. 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 is  
always active and must have a logic HIGH or LOW  
level applied to prevent excess ICC and ICCZ  
.
The SN74LVC8T245-Q1 is designed so that the  
control pins (DIR and OE) are supplied by VCCA  
.
This device is fully specified for partial-power-down  
applications using Ioff. The Ioff circuitry disables the  
outputs, preventing damaging current backflow  
through the device when it is powered down.  
The VCC isolation feature ensures that if either VCC  
input is at GND, all outputs are in the high-impedance  
state.  
To ensure the high-impedance state during power up  
or power down, OE should be tied to VCC through a  
pullup resistor; the minimum value of the resistor is  
determined by the current-sinking capability of the  
driver.
