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

The SN74LVCR16245A device is designed for asynchronous communication between data buses. All inputs and outputs have equivalent 26-Ω resistors that will slow the edges of the output and reduce switching noise caused by long capacitive etch runs or cables.

This device can be used as two 8-bit transceivers or one 16-bit transceiver. Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state.

For all available packages, see the orderable addendum at the end of the datasheet.
