DESCRIPTION/ORDERING INFORMATION

This 16-bit (dual-octal) noninverting bus transceiver is

designed for 2.7-V to 3.6-V VCC operation.

The SN74LVCR162245 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 upon 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 effectively are isolated.

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

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. Use of pullup or

pulldown resistors with the bus-hold circuitry is not recommended. The bus-hold circuitry is part of the input

circuit and is not disabled by OE or DIR.
