18-Bit Registers

ProductFeatures:

CommonFeatures:

• PI74FCT16823TandPI74FCT162823Tarehigh-speed,low

power devices with high current drive.

• VCC =5V±10%

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.

The PI74FCT16823T, PI74FCT162823T and PI74FCT162H823

are 18-bit wide registers with clock enable (xCLKEN) and clear

(xCLR) controls that make these devices especially suitable for

parity bus interfacing in high-performance systems. The devices

canbeoperatedastwo9-bitregistersorone18-bitregisterusingthe

control inputs. Signal pins are arranged in a flow-through

organization for ease of layout and hysteresis is designed into all

inputs to improve noise margin.

• Hysteresis on all inputs

• Packagesavailable:

– 56-pin240milwideplasticTSSOP(A)

– 56-pin300milwidepalsticSSOP(V)

PI74FCT16823TFeatures:

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

• Power off disable outputs permit “live insertion”

The PI74FCT16823T output buffers are designed with a Power-

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

devices are used as backplane drives.

• Typical VOLP (Output Ground Bounce) < 1.0V

atVCC =5V,TA =25°C

PI74FCT162823TFeatures:

• Balanced output drivers: ±24 mA

• Reduced system switching noise

• Typical V^OLP(Output Ground Bounce) < 0.6V

atVCC =5V,TA =25°C

The PI74FCT162823T 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.

PI74FCT162H823TFeatures:

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

• Eliminates the need for external pull-up resistors

The PI74FCT162H823T has “Bus Hold” which retains the input’s

last state whenever the input goes to high-impedance preventing

“floating”inputsandeliminatingtheneedforpull-up/downresistors.
