PI49FCT3805/PI49FCT3806
3.3V Fast CMOS Buffer/Clock Driver
Features
Description
ÎÎ3.3V version of PI49FCT805/806
Pericom Semiconductor’s 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. Each clock driver consist of
two banks of drivers, driving five outputs each from a standard
TTL compatible CMOS input.
ÎÎExtremely low output skew: 0.5ns
ÎÎMonitor ouput pin
ÎÎClock busing wih 3-state control
ÎÎTTL input and CMOS output compatible
ÎÎIndustrial operation at –40°C to 85°C
ÎÎExtremely low static power (1mW, typ.)
ÎÎHysteresis on all inputs
ÎÎPackaging (Pb-free & Green available):
àà 20-pin 150-mil wide QSOP (Q)
àà 20-pin 209-mil wide SSOP (H)

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.
3. VOH = VCC – 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.

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 3.3V, +25°C ambient.
3. Per TTL driven input (V IN = VCC – 0.6V); 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 Ic formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ΔICC DhNt + ICCD (fONO)
ICC = Quiescent Current
ΔICC = Power Supply Current for a TTL High Input (V IN = VCC – 0.6V)
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)
f O = Output Frequency
NO = Number of Outputs at fO
All currents are in milliamps and all frequencies are in megahertz.
