Pericom Semiconductor’s PI49FCT805T and PI49FCT2805T
are non-inverting clock drivers. Each clock driver consists of two banks of drivers, driving five outputs each from a standard
TTL-compatible CMOS input.
Extremely low output skew: 0.5ns
Monitor output pin
Clock busing with Hi-Z state control
TTL input and CMOS output compatible
Extremely low static power (1mW, typ.)
Hysteresis on all inputs
Device models available on request
Industrial Operation at -40ºC to +85ºC
Packaging (Pb-free & Green):
– 20-pin 209-mil wide SSOP (H)
– 20-pin 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
The PI49FCT2805T features a 25-Ohm on-chip resistor for
lower noise.

Typical values are at Vcc = 5.0V, +25°C ambient.
Per TTL driven input (Vin = 3.4V); all other inputs at Vcc or GND.
This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
Values for these conditions are examples of the Icc formula. These limits are guaranteed but not tested.
Ic =Iquiescent + Iinputs + Idynamic
Ic = Icc + DIcc DhNt + Iccd (fcp/2 + fiNi)
Icc = Quiescent Current
DIcc = 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.
