PI6C49X0204CWIEX

Clock Buffers, Drivers Overview

The PI6C49X0204CWIEX is a low skew, single-input to four-output clock buffer manufactured by Diodes Incorporated. It utilizes low power CMOS technology and operates within an industrial temperature range of -40°C to +85°C. The device supports supply voltages from 1.425V to 3.6V. Key electrical specifications include a maximum propagation delay of 5ns at 1.5V and 2.5ns at 3.3V, with output-to-output skew limited to ±250ps. The input clock pin is 3.6V tolerant, and the unit is housed in an 8-pin Wide SOIC package.

Clock Buffers, Drivers Procurement Notes

Verify the component against the official datasheet DS43291 Rev 1-2 to confirm technical parameters. Ensure the ordering suffix matches the required package and reel specifications. Confirm compliance with RoHS and halogen-free requirements as defined by the manufacturer's quality definitions before procurement.

Clock Buffers, Drivers Selection Notes

Select this component for designs requiring low skew distribution of a single clock signal to four destinations. Verify that the operating voltage falls within the 1.425V to 3.6V range. Consider the 3.6V tolerant input if interfacing with higher voltage logic levels. Ensure the PCB layout accommodates the 8-pin Wide SOIC package dimensions.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49X series of clock buffers from Diodes Incorporated. The specific model PI6C49X0204C provides a 1:4 fanout ratio. The 'W' indicates the Wide SOIC package, and 'IE' denotes lead-free and green packaging. It is distinct from other variants in the series that may offer different output counts or package types.

Clock Buffers, Drivers Replacement Considerations

Direct replacements must match the 1:4 fanout ratio, 8-pin Wide SOIC package, and compatible voltage ranges. Verify pin compatibility and electrical characteristics such as propagation delay and skew. Consult the manufacturer for automotive qualified alternatives if AEC-Q100 compliance is required.

Clock Buffers, Drivers FAQ

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the outputs. When the OE pin is pulled low, all four outputs are tri-stated.

Is the CLK input tolerant to 3.6V?

Yes, the CLK input pin is specified as 3.6V tolerant, allowing it to interface with higher voltage logic levels while the device operates at lower supply voltages.

What is the maximum output-to-output skew?

The maximum output-to-output skew is ±250ps, measured between any two outputs with equal loading at rising edges at VDD/2.
