description
This 16-bit to 32-bit registered bus exchanger is
designed for 2.3-V to 3.6-V V
CC
operation. 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.
The device provides synchronous data exchange
between the A and B 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, and 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.
Two mask bits are provided for both data bytes.
The D outputs are controlled by the active-low OE.
To ensure the high-impedance state during power
up or power down, OE should be tied to V
CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.
Active bus-hold circuitry is provided to hold
unused or floating data inputs at a valid logic level.
The SN74ALVCH16280 is characterized for
operation from –40
°
C to 85
°
C.
