AD246JY

Clock Buffers, Drivers Overview

The AD246JY is a clock driver integrated circuit manufactured by Analog Devices Inc., designed to distribute clock signals from a single 15 V supply. It features a nominal output frequency of 25 kHz with a 15 V peak-to-peak voltage swing. The device supports a maximum fan-out of 32 loads, such as the AD204 isolator, drawing 35 mA in an unloaded state. Packaged in a 4-lead SIP (AD246JY) or 14-lead DIP (AD246JN), it operates within a supply voltage range of 14.25 V to 15.75 V and functions across temperatures from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Single 15 V power supply operation with nominal 25 kHz clock output
• High current drive capability supporting up to 32 AD204 isolators
• Integrated supply bypass capacitor for simplified design
• Available in compact 4-lead SIP package (AD246JY)

Clock Buffers, Drivers Applications

• Driving multiple AD204 digital isolators in industrial systems
• Clock distribution in isolated data acquisition chains
• Power supply monitoring circuits requiring isolated clock signals

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to potential availability constraints. Confirm RoHS compliance status as indicated in distributor listings. Ensure proper handling for through-hole mounting during assembly. Check for end-of-life notifications or discontinuance updates prior to final procurement decisions.

Clock Buffers, Drivers Selection Notes

Select the AD246JY when a compact 4-lead SIP form factor is required for clock distribution. Choose this part over the AD246JN if board space is limited and fewer than 32 isolators are driven. Ensure the system supply voltage remains within the 14.25 V to 15.75 V range to maintain specified performance and fan-out capabilities.

Clock Buffers, Drivers Part Context

The AD246 belongs to the AD246 series of clock drivers. It is functionally identical to the AD246JN but differs in packaging. The JY suffix denotes the 4-lead SIP package, while JN denotes the 14-lead DIP package. Both variants share the same electrical specifications and internal circuitry.

Clock Buffers, Drivers Replacement Considerations

No direct public substitute part numbers are documented for the AD246JY. Designers may consider redesigning with modern clock buffers if the AD246 is discontinued, as no equivalent legacy replacement is listed.
