• Signal distribution networks
• High-speed digital systems requiring low skew

Clock Buffers, Drivers Procurement Notes

Verify the component status as the datasheet indicates potential discontinuation or end-of-life notifications for specific variants. Confirm the 'C' speed grade corresponds to the 3.5ns propagation delay specification. Ensure the 'QEX' suffix matches the required 20-pin QSOP tape and reel packaging format.

Clock Buffers, Drivers Selection Notes

Select this part when a single clock source must drive up to ten loads with minimal timing distortion. The 0.25ns skew guarantee makes it suitable for high-frequency applications where phase alignment between outputs is critical. Verify that the system voltage aligns with the 5.0V nominal supply requirement.

Clock Buffers, Drivers Part Context

This component belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. It is functionally related to the PI49FCT2807T but offers optimized speed grades. The 'CT' designation specifies the commercial/industrial temperature range and the C-speed grade for propagation delay.

Clock Buffers, Drivers Replacement Considerations

Direct pin-compatible replacements include other variants within the PI49FCT807 family such as PI49FCT807TQEX (Blank speed grade) or PI49FCT807CTSEX (SOIC package). Verify that alternative packages maintain the same thermal and mechanical constraints.

Clock Buffers, Drivers FAQ

What is the maximum propagation delay for the PI49FCT807CTQE?

The maximum propagation delay (tPLH/tPHL) from input A to any output B0-B9 is 3.5ns under standard test conditions.

Does the PI49FCT807CTQE have output enable controls?

No, the PI49FCT807T is a non-inverting clock driver without 3-state output enable inputs; all ten outputs are active based on the input signal.

What is the typical output high voltage level?

The typical output high voltage (VOH) is 3.3V when VCC is at its minimum value and the output current is -15.0mA.
