ICS542M

Clock Buffers, Drivers Overview

The ICS542M is a clock divider IC manufactured by Renesas Electronics Corporation (formerly IDT). It accepts an input clock up to 156 MHz and produces divided outputs of /2, /4, /6, /8, /12, or /16. The device features two CMOS outputs with low skew (500 ps), where one output is a divide-by-two of the other. Operating voltages range from 3.0 V to 5.5 V. It includes power-down and Output Enable (OE) functions. The component is housed in an 8-pin SOIC package.

Clock Buffers, Drivers Feature Summary

• Input frequency up to 156 MHz
• Low skew outputs (500 ps typical)
• Divide ratios: /2, /4, /6, /8, /12, /16
• Power-down mode and Output Enable

Clock Buffers, Drivers Applications

• Clock distribution networks requiring frequency division
• Systems needing low-skew dual clock outputs
• General-purpose clock generation supporting commercial temperature ranges

Clock Buffers, Drivers Procurement Notes

Verify RoHS compliance status as non-green parts reached End-of-Life on May 13, 2010. Confirm current availability through authorized distributors, as standard versions may be discontinued. Check for LF suffix variants if lead-free requirements are mandatory for the specific application.

Clock Buffers, Drivers Selection Notes

Select based on required operating temperature range; 'M' suffix denotes commercial range (0°C to +70°C), while 'MI' indicates industrial range (-40°C to +85°C). Ensure supply voltage matches 3.3 V or 5 V specifications. Verify packaging needs, as tubes and tape/reel options exist for different quantities.

Clock Buffers, Drivers Part Context

The ICS542 is part of the IDT/ICS clock divider family. Related components include the ICS541 and ICS543 for other divider configurations, and the ICS501, ICS502, ICS511, ICS512, and ICS525 for clock multiplier applications.
