description
The SN74ALVCHG162282 is an 18-bit to 36-bit
registered bus exchanger. This device 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 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 direction-control (DIR) input. DIR is registered
to synchronize the bus direction changes with the
clock.
