Description

This 32-bit noninverting bus transceiver SN74LVC32245 is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVC32245 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.

This device SN74LVC32245 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 are effectively isolated.

SN74LVC32245 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.

This device SN74LVC32245 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.

To ensure the high-impedance state during power up or power down, SN74LVC32245 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.
