3.3V 16-BIT REGISTERED TRANSCEIVERS

PI74LPT16952

Fast CMOS 3.3V 16-Bit Registered Transceivers

Product Features

Product Description

• CompatiblewithLCX™andLVT™familiesofproducts

Pericom Semiconductor’s PI74LPT series of logic circuits are

producedintheCompany’sadvanced0.6micronCMOStechnology,

achieving industry leading speed grades.

• Supports 5V Tolerant Mixed Signal Mode Operation

– Input can be 3V or 5V

– Output can be 3V or connected to 5V bus

The PI74LPT16952 is a 16-bit registered transceivers organized

with two sets of eight D-type latches with separate input and output

controls for each set. For data flow from A to B, for example, the A-

to-B Enable (xCEAB) input must be LOW to enter data from xAx.

ThedatapresentontheAportwillbeclockedontheBregisterwhen

xCLKAB toggles from LOW-to-HIGH. The xOEAB control

performs the output enable function on the B port. Control of data

from B to A is similar, but uses the xCEAB, xCLKAB, and xOEAB

inputs. By connecting the control pins of the two independent

transceivers together, a full 16-bit operation can be achieved. The

outputbuffersaredesignedwithaPower-Offdisableallowing“live

insertion” of boards when used as backplane drivers.

• Advanced Low Power CMOS Operation

• Excellent output drive capability:

Balanced drives (24 mA sink and source)

• Pin compatible with industry standard double-density

pinouts

• Low ground bounce outputs

• Hysteresis on all inputs

• Industrial operating temperature range: –40°C to +85°C

• Multiple center pins and distributed Vcc/GND pins

minimize switching noise

allowing this device to be used as a translator in a mixed

3.3/5.0V system.
