Product Description:

Pericom Semiconductor’s PI74FCT series of logic circuits are pro-

duced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

• PI74FCT16952T,PI74FCT162952T,andPI74FCT2H952T

are high-speed,

low power devices with high current drive

• VCC =5V±10%

ThePI74FCT16952T,PI74FCT162952T,and PI74FCT162H952T

are 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 in order to enter data from xAx. The

data present on the A port will be clocked on the B register when

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 xCEBA, xCLKBA, and xOEBA

inputs. By connecting the control pins of the two independent

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

output buffers are designed with a Power-Off disable allowing

“live insertion” of boards when used as backplane drivers.

• Hysteresis on all inputs

• Packagesavailable:

– 56-pin240milwideplasticTSSOP(A)

– 56-pin300milwide plasticSSOP(V)

PI74FCT16952TFeatures:

• High output drive: I^OH= –32 mA; IOL = 64 mA

• Power off disable outputs permit “live insertion”

• Typical VOLP (Output Ground Bounce) < 1.0V

atVCC =5V,TA =25°C

PI74FCT162952TFeatures:

The PI74FCT16952T output buffers are designed with a Power-

Off disable function allowing “live insertion” of boards when used

as backplane drivers.

• Balanced output drivers: ±24 mA

• Reduced system switching noise

The PI74FCT162952T has ±24 mA balanced output drivers. It is

designed with current limiting resistors at its outputs to control the

output edge rate resulting in lower ground bounce and undershoot.

This eliminates the need for external terminating resistors for most

interface applications.

• Typical VOLP (Output Ground Bounce) < 0.6V

atVCC =5V,TA =25°C

PI74FCT162H952TFeatures:

• Bus Hold retains last active bus state during 3-state

• Eliminates the need for external pull-up resistors

The PI74FCT162H952T has “Bus Hold” which retains the input’s

last state whenever the input goes to high-impedance preventing

“floating”inputsandeliminatingtheneedforpull-up/downresistors.
