description  
This octal bus transceiver is designed for 2.7-V to 3.6-V V  
operation.  
CC  
The SN74LVCZ245A 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 output-enable (OE) input can be used to disable the device so the buses are  
effectively isolated.  
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.  
When V  
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
through a pullup resistor;  
CC  
This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry  
off  
off  
disables the outputs, preventing damaging current backflow through the device when it is powered down. The  
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.  
The SN74LVCZ245A is characterized for operation from –40°C to 85°C.
