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: -40C to +85C 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)
Description
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 ................................................................. -65C to +150C Ambient Temperature with Power Applied ................................ -40C to +85C Input Voltage to GND Potential (Inputs & VCC Only) .................. -0.5V to 5.5V Output Voltage to GND Potential (Outputs & I/O Only)...-0.5V to +VCC +0.5V VCC Input Voltage........................................................................ -0.5V to +4.6V
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, +25C 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.
