PI6C49CB04AJWEX

Clock Buffers, Drivers Overview

The PI6C49CB04AJWEX is an industrial-grade, low-skew, 1-to-4 fanout buffer manufactured by Diodes Incorporated. It utilizes low-power CMOS technology and operates within a supply voltage range of 1.425 V to 3.6 V. The device features a 3.6 V tolerant input clock and provides four LVCMOS/LVTTL outputs with guaranteed part-to-part skew characteristics. Maximum output frequency reaches 160 MHz at lower voltages, while propagation delay varies from 2.5 ns to 5 ns depending on the supply voltage. It is housed in an 8-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• Industrial grade operation (-40°C to +105°C) with low skew outputs (±250 ps typical).
• Wide operating voltage support: 1.5V, 1.8V, 2.5V, and 3.3V.
• 3.6V tolerant CLK input allows interfacing with higher voltage sources.
• Output Enable pin (OE) tri-states outputs when driven low.

Clock Buffers, Drivers Applications

• Clock distribution networks requiring well-defined performance and repeatability.
• Low power CMOS logic systems utilizing LVCMOS or LVTTL standards.
• Industrial electronic equipment operating across extended temperature ranges.

Clock Buffers, Drivers Procurement Notes

Verify that the specific ordering suffix matches the required configuration. The 'J' suffix indicates Industrial Grade qualification, while 'WEX' denotes the 8-pin SOIC package in Tape & Reel format. Confirm RoHS compliance and Halogen-free status requirements against project specifications before finalizing procurement orders.

Clock Buffers, Drivers Selection Notes

Select this component for applications demanding low skew and high repeatability in clock distribution. Ensure the system voltage aligns with the supported rails (1.5V, 1.8V, 2.5V, or 3.3V). Note that maximum frequency decreases to 100 MHz when operating at 3.3V. Verify thermal management capabilities if operating near the upper temperature limit of +105°C.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49CB series of low-skew fanout buffers. The PI6C49CB04AJ variant specifically targets industrial environments, distinguishing it from automotive-qualified counterparts like the PI6C49CB04AQ which meet AEC-Q100 standards. It serves as a signal integrity solution for multi-load clock trees.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include the PI6C49CB04AWEX (Commercial Grade) for non-industrial use. For automotive applications, the PI6C49CB04AQ2WEX is the qualified alternative. Cross-family substitutes require verification of voltage levels, package dimensions, and electrical parameters.
