DESCRIPTION/ORDERING INFORMATION (CONTINUED)
SN74LVCZ32245A
32-BIT BUS TRANSCEIVER
WITH 3-STATE OUTPUTS
SCES423 – JANUARY 2003 – REVISED JUNE 2005
This device can be used as four 8-bit transceivers, two 16-bit transceivers, or one 32-bit transceiver. It allows
data transmission 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 that the buses
effectively are 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 VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, 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.
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
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.
