3.3VversionofPI49FCT805/806

Extremelylowoutputskew:0.5ns

Monitor ouput pin

Pericom Semiconductors PI49FCT series of logic circuits are

produced using the Companys advanced submicron CMOS

technology, achieving industry leading speed grades.

Clock busing wih 3-state control

TTL inpu and CMOS output compatible

Industrial operation at40°C to 85°C

Extremelylowstaticpower(1mW,typ.)

Hysteresis on all inputs

The PI49FCT3805 is a 3.3V non-inverting clock driver and the

PI49FCT3806 is a 3.3V inverting clock driver designed with two

independent groups of buffers. These buffers have 3-state Output

Enable inputs (active LOW) with a 1-in, 5-out configuration per

group.Eachclockdriverconsistoftwobanksofdrivers,drivingfive

outputs each from a standard TTL compatible CMOS input.

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at V_CC= 3.3V, +25°C ambient and maximum loading.

3. V_OH= V_CC– 0.6V at rated current.

4. This parameter is determined by device characterization but is not production tested.

5. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
