Description

This octal bus transceiver SN74LVCR2245A is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCR2245A 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 (<a href="#" style="text-decoration:overline;">OE</a>) input can be used to disable the device so the buses are effectively isolated.

SN74LVCR2245A All outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.

SN74LVCR2245A 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.

To ensure the high-impedance state during power up or power down, <a href="#" style="text-decoration:overline;">OE</a> 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.

The SN74LVCR2245A is characterized for operation from 40°C to 85°C.
