ADVANCE INFORMATION

PI74AVC16646

PI74AVCH16646

16-Bit Bus Transceiver and Register

with 3-State Outputs

ProductDescription

Product Features

Pericom Semiconductors PI74AVC series of logic circuits are

produced using the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

· Designed for low voltage operation,

V_CC= 1.65V to 3.6V

· Sub 2.0ns delays at 2.5V and 3.3V

· Dynamic Impedance Control on outputs,

current drive > ±24mA at 2.5V_CC

This 16-bit bus transceiver and register can be used as two

8-bit transceivers or one 16-bit transceiver. Data on the A or B bus

is clocked into the registers on the low-to-high transition of the

appropriate Clock (CLKAB or CLKBA) input. Four fundamental

bus-management functions can be performed.

· Patented noise reduction circuit

· I/O Tolerant to 3.6V, Inputs and Outputs for

mixed voltage systems

OutputEnable(OE)andDirectionControl(DIR)inputsareprovided

to control the transceiver functions. In the transceiver mode, data

present at the high-impedance port may be stored in either register

orinboth. TheSelectControl(SABandSBA)inputscanmultiplex

stored and real-time (transparent mode) 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. DIRdetermineswhichbusreceivesdatawhenOEisLOW. In

theisolationmode(OEHIGH), Adatamaybestoredinoneregister

and/or B data may be stored in the other register.

· Supports live insertion

· Industrial operation at -40°C to +85°C

· Available Packages:

48-pin 240 mil wide plastic TSSOP (A48)

48-pin 173 mil wide plastic TVSOP (K48)

When an output function is disabled, the input function is still

enabled and may be used to store and transmit data. Only one of the

two buses, A or B, can be driven at a time.

To ensure the high-impedance state during power up or power

down, OE should be tied to V through a pullup resistor; the

minimumvalue of the resistor is determined by the current-sinking

capability of the driver.

The PI74AVCH16646 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.
