Product Features

CommonFeatures:

ProductDescription

Pericom Semiconductors PI74FCT series of logic circuits are pro-

duced using the Companys advanced 0.6 micron CMOS

technology, achieving industry leading speed grades.

PI74FCT16373T, PI74FCT162373T, and

PI74FCT162H373T are high-speed,

low power devices with high current drive.

Vcc = 5V ±10%

Hysteresis on all inputs

Packages available:

48-pin 240 mil wide plastic TSSOP (A)

48-pin 300 mil wide plastic SSOP (V)

PI74FCT16373T Features:

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

Power off disable outputs permit "live insertion"

ThePI74FCT16373T,PI74FCT162373T,andPI74FCT162H373T

are 16-bit transparent latches designed with 3-state outputs and are

intended for bus oriented applications. The Output Enable and

Latch Enable controls are organized to operate as two 8-bit latches

orone16-bitlatch. WhenLatchEnable(LE)isHIGH,theflip-flops

appear transparent to the data. The data that meets the set-up time

when LE is LOW is latched. When OE is HIGH, the bus output is

in the high impedance state.

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

PI74FCT162373TFeatures:

ThePI74FCT16373ToutputbuffersaredesignedwithaPower-Off

disable allowing live insertion of boards when used as backplane

drivers.

Balanced output drivers: ±24 mA

Reduced system switching noise

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

atVCC =5V,TA =25°C

PI74FCT162H373TFeatures:

The PI74FCT162373T 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

Eliminates the need for external pull-up resistors

The PI74FCT162H373T has Bus Hold which retains the inputs

last state whenever the input goes to high-impedance preventing
