PI74AVC+16841

2.5V 20-Bit Bus Interface D-Type

Latch with 3-State Outputs

Product Features

ProductDescription

PI74AVC+16841 is designed for low-voltage operation,

Pericom Semiconductors PI74AVC+ series of logic circuits are

produced using the Companys advanced submicron CMOS

technology, achieving industry leading speed.

V_CC= 1.65V to 3.6V

True ±24mA Balanced Drive @ 3.3V

I_OFFsupports partial power-down operation

3.6V I/O Tolerant Inputs and Outputs

ThePI74AVC+16841,a20-bitbus-interfaceD-typelatch, isdesigned

for1.65Vto3.6VV operation.

The device features 3-state outputs designed specifically for

driving highly capacitive or relatively low-impedance loads.

It is particularly suitable for implementing buffer registers,

unidirectional bus drivers, and working registers.

All outputs contain a patented DDC

(Dynamic DriveControl) circuit that reduces noise without

degrading propagation delay.

Industrial operation: 40°C to +85°C

Available Packages:

The device can be used as two 10-bit latches or one

20-bitlatch(transparentD-type).ThedevicehasnoninvertingData

(D) inputs and provides true data at its outputs. While the Latch

Enable(1LEor2LE)inputisHIGH,theQoutputsofthecorresponding

10-bit latch follow the D inputs. When LE is taken LOW, the Q

outputs are latched at the levels set up at the D inputs.

LogicBlockDiagram

A buffered Output Enable (1OE or 2OE) input can be used to place

theoutputsofthecorresponding10-bitlatchineitheranormallogic

state (high or low logic levels) or a high-impedance state. In that

state, outputs neither load nor drive the bus lines significantly.

of the latches. Old data can be retained or new data can be entered

while the outputs are in the high-impedance state.

1Q1

1D1

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.
