PI49FCT805T/2805T Logic Block Diagram
PI49FCT806T Logic Block Diagram
The PI49FCT805T and PI49FCT2805T are non-inverting clock
drivers. The PI49FCT806T is an inverting clock driver designed with
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.
The PI49FCT2805T also features a 25-ohm on-chip resistor for lower
noise.

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at Vcc = 5.0V, +25°C ambient.
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)

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)
