PI6C10804
1.8V/2.5V, 250MHz, 1:4 Networking Clock Buffer
1.8V Absolute Maximum Ratings (Above which the useful life may be impaired. For user guidelines only, not tested.)
Note:
Storage Temperature........................................................... –65°C to +150°C Stresses greater than those listed under MAXIMUM
VDD Voltage ..........................................................................–0.5V to +2.5V
Output Voltage (max 2.5V) .......................................... –0.5V to VDD+0.5V
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
Input Voltage (max 2.5V) ............................................. –0.5V to VDD+0.5V
indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.
1.8V DC Characteristics (Over Operating Range: VDD = 1.8V ± 0.15V, TA = -40° to 85°C)

Notes:
1. For Max. or Min. conditions, use appropriate operating Vdd and Ta values.
2. Typical values are at VCC = 1.8V, +25°C ambient and maximum loading.
3. This parameter is determined by device characterization but is not production tested.

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew measured at worse cast temperature (max. temp).
4. Identical conditions: loading, transitions, supply voltage, temperature, package type and speed grade.
