ISL90460TIE527Z-TK

Digital Potentiometers Overview

The ISL90460TIE527Z-TK is a single volatile 32-tap digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.7V to 5.5V and features a total resistance (RTOTAL) of 100kΩ with a typical temperature coefficient of 35ppm/°C. The device utilizes a 2-pin Up/Down interface for wiper position control and includes volatile memory that retains settings only while powered. It is housed in a 5-lead SC-70 package and supports an industrial operating temperature range from -40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and Pb-free plus anneal material specifications. Ensure the ordering suffix matches the required resistance value and package type. Check for current availability status as older variants may be discontinued.

Digital Potentiometers Selection Notes

Select based on required total resistance (10kΩ, 50kΩ, or 100kΩ) and package preference (SC-70 or SOT-23). Note that this is a volatile device; wiper position resets upon power loss. Ensure supply voltage stays within 2.7V to 5.5V. Consider replacement parts like ISL90461 if non-volatile memory is required.

Digital Potentiometers Part Context

The ISL90460 is part of the Intersil XDCP™ family, now under Renesas Electronics. It serves as a solid-state alternative to mechanical potentiometers in applications requiring digital adjustment. The specific 'T' suffix indicates the 100kΩ resistance variant, while 'E527Z' denotes the SC-70 package and tape/reel packaging.

Digital Potentiometers Replacement Considerations

The datasheet explicitly recommends ISL90460TIH527Z-TK as a replacement for discontinued versions. Other potential substitutes include ISL90461 and ISL90462, which offer similar functionality but may differ in memory volatility or pinout configurations.
