Description
Pericom Semiconductor's PI49FCT32807 is a 3.3V very lowskew clock buffer that produces ten outputs from a single lowcapacitance input. Excellent output signals to power and ground ratio minimize power and ground noise, and also improves output performance. The PI49FCT32807 integrates series damping resistors on all outputs.

Maximum Ratings
(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 Supply Voltage to Ground Potential (Inputs & VCC Only).....-0.5V to +7.0V Supply Voltage to Ground Potential (Outputs & D/O Only) ..-0.5V to +7.0V DC Input Voltage ....................................................................-0.5V to +7.0V DC Output Current............................................................................... 120mA Power Dissipation ................................................................................... 0.5W
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.
