Description

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.

The PI49FCT2805T features a 25-Ohm on-chip resistor for

lower noise.

Notes:

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

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.
