Pericom Semiconductors PI74AVC series of logic circuits are

produced using the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

The 12-bit to 24-bit multiplexed bus exchanger is designed 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

through a pullup resistor, the

minimum value of the resistor is determined by the current-sinking

capability of the driver.

The PI74AVCH16271 has Bus Hold which retains the data

inputs last state whenever the data input goes to high-

impedance preventing floating inputs and eliminating the need

for pullup/down resistors.
