PI74ALVCT16260

12-Bit To 24-Bit Multiplexed D-Type Latch

with 3-STATE Outputs

ProductDescription

ProductFeatures

Pericom Semiconductor’s PI74ALVCT series of logic circuits are

producedintheCompany’sadvanced0.5micronCMOStechnology,

achieving industry leading speed.

• PI74ALVCT16260isdesignedforlowvoltageoperation

• V =2.3Vto3.6V

• 5V tolerant inputs and outputs

• Hysteresis on all inputs

ThePI74ALVCT16260isa12-bitto24-bitmultiplexedD-typelatch

designed for 2.3V to 3.6 Vcc operation. It is used in applications

where two separate datapaths must be multiplexed onto, or

demultiplexed from, a single data path.

• Typical V

(Output Ground Bounce)

<0.8VatV =3.3V,T =25°C

• Typical V

(Output V Undershoot)

OHV

Typical applications include multiplexing and/or demulti-plexing

address and data information in microprocessor or bus-interface

applications. This device is also useful in memory-interleaving

applications.

<2.0VatV =3.3V,T =25°C

• Industrial operation at 40°C to +85°C

• Packagesavailable:

56-pin300milwideplasticSSOP(V)

Three12-bitI/Oports(A1-A12,1B1-1B12,and2B1-2B12)areavailable

for address and/or data transfer. The output-enable (OE1B, OE2B,

and OEA) inputs control the bus transceiver functions. The OE1B

and OE2B control signals also allow bank control in the A-to-B

direction.

Address and/or data information can be stored using the internal

storagelatches.Thelatch-enable(LE1B,LE2B,LEA1B,andLEA2B)

inputs are used to control data storage. When the latch-enable input

is HIGH, the latch is transparent. When the latch-enable input goes

LOW, the data present at the inputs is latched and remains latched

until the latch-enable input is returned HIGH.

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

driver.
