description/ordering informationThis 16-bit (dual-octal) noninverting bus
transceiver is designed for 2.7-V to 3.6-V VCCoperation.
The SN74LVCZ16245A is designed for
asynchronous communication between data
buses. The control-function implementation
minimizes external timing requirements.
This device can be used as two 8-bit transceivers
or one 16-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
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 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.
