DESCRIPTION/ORDERING INFORMATION  
The SN54LVCH245A octal bus transceiver is designed for 2.7-V to 3.6-V VCC operation, and the  
SN74LVCH245A octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
These devices are designed for asynchronous communication between data buses. These devices transmit 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 output-enable (OE) input can be used to disable the device so the buses are effectively isolated.  
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the  
outputs, preventing damaging current backflow through the devices when they are powered down.  
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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or  
pulldown resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry is part of the input  
circuit and is not disabled by OE or DIR.
