This 16-bit (dual-octal) noninverting bus transceiver is
designed for 2.7-V to 3.6-V V
CC
operation.
The SN74LVCR162245 is designed for asynchronous
communication between data buses. The
control-function implementation minimizes external
timing requirements.
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- 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.
