Product Features
ProductDescription
Extremelylowoutputskew:0.5ns
Monitor output pin
Pericom Semiconductors PI49FCT series of logic circuits are
produced using the Companys advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
Clock busing with Hi-Z state control
TTL input and CMOS output compatible
Extremelylowstaticpower(1mW,typ.)
Hysteresis on all inputs
The PI49FCT805T and PI49FCT2805T are non-inverting clock
drivers.ThePI49FCT806Tisaninvertingclockdriverdesignedwith
two independent groups of buffers that have Hi-Z state Output
Enable inputs (active LOW) with a 1-in, 5-out configuration per
group. Each clock driver consists of two banks of drivers, driving
five outputs each from a standard TTL-compatible CMOS input.

3. Per TTL driven input (VIN = 3.4V); all other inputs at Vcc or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the Icc formula. These limits are guaranteed but not tested.
6. IC =IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ∆ICC DHNT + ICCD (fCP/2 + fINI)
ICC = Quiescent Current
∆ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fI = Input Frequency
NI = Number of Inputs at fI
All currents are in milliamps and all frequencies are in megahertz.
