description
The SN74ALVCH16282 is an 18-bit to 36-bit
registered bus exchanger designed for 2.3-V to
3.6-V V
CC
operation. This part is intended for use
in applications where data must be transferred
from a narrow high-speed bus to a wide
lower-frequency bus. It is designed specifically for
low-voltage (3.3-V) V
CC
operation.
The device provides synchronous data exchange
between the two ports. Data is stored in the
internal registers on the low-to-high transition of
the CLK input. For data transfer in the B-to-A
direction, SEL selects 1B or 2B data for the A
outputs.
For data transfer in the A-to-B direction, a
two-stage pipeline is provided in the 1B path, with
a single storage register in the 2B path. Data flow
is controlled by the active-low output enable (OE)
and the DIR input. The DIR control pin is
registered to synchronize the bus direction
changes with the clock.
Active bus-hold circuitry is provided to hold
unused or floating data inputs at a valid logic level.
The SN74ALVCH16282 is characterized for
operation from –40
°
C to 85
°
C.
