description
The SN74ALVCH16282 is an 18-bit to 36-bit
registered bus exchanger designed for 1.65-V to
3.6-V V
CC
operation.
This device is intended for use in applications in
which 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 clock (CLK) input. For data transfer in the
B-to-A direction, the select (SEL) input 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.
