Description
Pericom Semiconductor's PI49FCT3807 is a 3.3V 1-to-10 clock driver. This low skew clock driver features one input and ten outputs fanout. The large fanout from a single input line reduces loading on input clock. TTL level ouputs reduce noise levels on the part. Typical applications are clock and signal distribution.

Input Hysteresis
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.
