PI74ALVCH16863

18-Bit Transceiver with 3-State Outputs

Logic Block Diagram

Product Description

Pericom Semiconductors PI74ALVCH series of logic circuits are
produced in the Companys advanced 0.5 micron CMOS technology,
achieving industry leading speed.

The PI74ALVCH16863 is an 18-bit noninverting transceiver designed
for synchronous communication between data buses. The control­function implementation minimizes external timing requirements.

The PI74ALCH16863 can be used as two 9-bit transceivers or one 18­bit transceiver.They allow data transmission from the A bus to the
B bus or from the B bus to the A bus, depending on the logic level
at the output-enable (OEAB or OEBA) inputs.

To ensure the high-impedance state during power up or power down,
OE should be tied to Vcc through a pull-up resistor; the minimum
value of the resistor is determined by the current-sinking capability
of the driver.

The PI74ALVCH16863 has Bus Hold which retains the data
inputs last state whenever the data input goes to high-impedance
preventing floating inputs and eliminating the need for pullup/
down resistors.
