2.5V 16-Bit Bus Transceiver and

Product Features

ProductDescription

PI74ALVTC16652isdesignedforlowvoltageoperation,

Pericom Semiconductors PI74ALVTC series of logic circuits are

produced using the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

Packagesavailable:

Complementary Output Enable (OEAB and OEBA) inputs are

provided to control the transceiver functions. Select Control (SAB

and SBA) inputs are provided to select whether real-time or stored

dataistransferred.Alowinputlevelselectsreal-timedata,andahigh

input level selects stored data. Circuitry used for Select Control

eliminates the typical decoding glitch that occurs in a multiplexer

during the transition between stored and real-time data.

Data on the A or B bus, or both, can be stored in the internal D flip-

flopsbylow-to-hightransitionsattheappropriateclock(CLKABor

CLKBA) inputs regardless of the levels on the Select Control or

Output Enable inputs. When SAB and SBA are in the real-time

transfer mode, it also is possible to store data without using the

internal D-type flip-lops by simultaneously enabling OEAB and

OEBA. Inthisconfiguration, eachoutputreinforcesitsinput. Thus,

whenallotherdatasourcestothetwosetsofbuslinesareinthehigh-

impedance state, each set of bus lines remains at its last level

configuration.

Toensurethehigh-impedancestateduringpoweruporpowerdown,

OEBA should be tied to Vcc through a pull-up resistor and OEAB

should be tied to GND through a pull-down resistor; the minimum

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

sourcing capability of the driver.

The family offers both I/O Tolerant, which allows it to operate in

mixed 1.65/3.6V systems, and Bus Hold, which retains the data

inputs last state preventing floating inputs and eliminating the

need for pullup/down resistors.
