Product Description
Pericom Semiconductor’s PI74AVC series of logic circuits are
produced using the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
This 12-bit to 24-bit multiplexed bus exchanger is designed for 2.3V
to 3.6V V
CC
operation.
The PI74ALVCH16271is intended for applications in which two
separate data paths must be multiplexed onto, or demultiplexed
from, a single data path. This device is particularly suitable as an
interface between conventional DRAMs and high-speed
microprocessors
Data is stored in the internal A-to-B registers on the low-to-high
transition of the clock (CLK) input, provided clock-enable (CLKENA)
inputs are low. Proper control of these inputs allows two sequential
12-bit words to be presented as a 24-bit word on the B port.
To maximize memory access throughput, transparent latches in
the B-to-A path allow asynchronous operation. These latches
transfer data when the latch-enable (LE) inputs are low. The select
(SEL) line selects 1B or 2B data for the A outputs. Data flow is
controlled by the active-low output enables (OEA, OEB).
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.
