Description

This 16-bit (dual-octal) noninverting bus transceiver SN74LVCR16245A is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCR16245A is designed for asynchronous communication between data buses. The control-function implementation minimizes external-timing requirements.

This device SN74LVCR16245A 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 disable the device so that the buses are effectively isolated.

SN74LVCR16245A All outputs, which are designed to sink up to 12 mA, include equivalent 26- series resistors to reduce overshoot and undershoot.

SN74LVCR16245A Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.

To ensure the high-impedance state during power up or power down, SN74LVCR16245A 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 SN74LVCR16245A 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.
