Description

Pericom Semiconductors PI49FCT series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving speeds up to 133 MHz, low-power dissipation, and output skew less than 250ps.

The PI49FCT32807 is a 3.3V very low-skew clock buffer that produces ten outputs from a single low-capacitance 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.

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.
