Product Features

Common Features

• PI74FCT16541T, PI74FCT162541T, and

PI74FCT162H541T are high-speed,

low power devices with high current drive

• V^CC= 5V ±10%

• Hysteresis on all inputs

• Packages available

– 48-pin 240 mil wide plastic TSSOP (A48)

PI74FCT16541T Features

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

• Power off disable outputs permit “live insertion”

• Typical V^OLP(Output Ground Bounce) < 1.0V

at V^CC= 5V, TA = 25°C

PI74FCT162541T Features

• Balanced output drivers: ±24 mA

• Reduced system switching noise

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

at VCC = 5V, TA = 25°C

Product Description

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

ducedintheCompany’sadvanced 0.6/0.8 micron CMOStechnology,

achieving industry leading speed grades.

ThePI74FCT16541T,PI74FCT162541T,andPI74FCT162H541T

arenon-inverting16-bitbuffer/linedriversdesignedforapplications

driving high capacitance loads and low impedance backplanes.

Thesehigh-speed,low-powerdevicesofferbus/backplaneinterface

capabilityandaflow-throughorganizationforeaseofboardlayout.

They are designed with three-state controls to operate in a Dual-

Byte, or a single 16-bit word mode.

The PI74FCT16541T output buffers are designed with a Power-

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

backplane drivers.

The PI74FCT162541T 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.

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

The PI74FCT162H541T has “Bus Hold” which retains the input’s

last state whenever the input goes to high-impedance preventing

“floating”inputsandeliminatingtheneedforpull-up/downresistors.

• Eliminates the need for external pull-up resistors
