PI49FCT3805D
3.3V, 2 x 1:5 CMOS Clock Driver
Description
Pericom Semiconductor’s PI49FCT3805D is composed of non-
inverting drivers. The outputs are congured into 2 groups of
one-in, ve-out with independent output enable. Group B has an
extra MON output. Excellent output signals to power and ground
ratio minimize power and ground noise and also improves output
performance.
Features
• Low output skew: <200ps
• Switching frequency up to 166 MHz
• Fast output rise/fall time: <1.0ns
• Low propagation delay: <2.5ns
• Low input capacitance: <6.0pF
• Balanced CMOS outputs
• Industrial Temperature: –40°C to +85°C
• 3.3V ±10% operation, 5V Input Tolerant
• Packaging (Pb-free & Green available):
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above those
indicated in the operational sections of this specication
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Notes:
1. For Max. or Min. conditions, use appropriate value specied 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.
