DESCRIPTION/ORDERING INFORMATION
This 12-bit to 24-bit bus exchanger is designed for
1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH16271 is intended for applications in
which two separate data paths must be multiplexed
onto, or demultiplexed from, a single data path. This
device
is
particularly
suitable
between
conventional
DRAMs
microprocessors.

To ensure the high-impedance state during power up or power down, the output enables should be tied to V
through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the
driver.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
