description
The SN74ALVCHR162282 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.
The outputs, which are designed to sink up to
12mA, 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.
The SN74ALVCHR162282 is characterized for
operation from –40
°
C to 85
°
C.
