Description
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 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)
– 20-pin 173-mil wide TSSOP (L)
Pericom Semiconductor’s PI49FCT3805D/E is composed of
non-inverting drivers. The outputs are configured into 2 groups of
one-in, five-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.

(Above which the useful life may be impaired. For user guidelines, not tested.)
Storage Temperature ................................................................. –65°C to +150°C
Ambient Temperature with Power Applied ................................ –40°C to +85°C
Input Voltage to GND Potential (Inputs & VCC Only) .................. –0.5V to 5.5V

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 specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

Notes:
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.
