Product details
Overview
ISL90460TIE527Z-TK from Intersil is a volatile 32-tap digitally controlled potentiometer (XDCP) configured as a rheostat with RH-to-GND variable resistance, 100kΩ end-to-end value, ±35ppm/°C tempco, and 2-pin Up/Down interface. It operates from 2.7V to 5.5V and supports LCD contrast control and sensor biasing in industrial environments.
For engineers reviewing the ISL90460TIE527Z-TK datasheet, ISL90460TIE527Z-TK pinout, ISL90460TIE527Z-TK application, or ISL90460TIE527Z-TK equivalent, key selection criteria include wiper resolution (32 taps), volatile memory behavior, SC-70 package constraints, and compatibility with low-power bias adjustment circuits requiring <25µA active current.
Technical Context
The ISL90460TIE527Z-TK implements a 31-element resistor array with electronic wiper switching controlled by CS and U/D inputs, enabling discrete tap selection without serial protocol overhead. Its volatile counter retains position only while powered and resets on power-up.
Wiper movement is edge-triggered on U/D toggling after CS assertion, with non-wrapping behavior at endpoints and 1µs output settling time. The device functions exclusively as a two-terminal variable resistor (RH-to-GND), not a three-terminal potentiometer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 100kΩ - defines maximum RH-to-GND resistance; sets gain/bias scaling range in analog circuits |
| Wiper taps | 32 - provides 31-step resolution for fine analog parameter tuning (e.g., laser diode bias) |
| Tempco | ±35ppm/°C - ensures stable resistance over -40°C to +85°C industrial temperature range |
| VDD range | 2.7V to 5.5V - enables direct interface with 3.3V and 5V logic/system rails |
| Active current | 25µA max - minimizes power impact in always-on sensor conditioning paths |
| Standby current | 0.3µA - supports ultra-low-quiescent operation during system sleep modes |
| Interface | 2-pin Up/Down - eliminates need for clock/data lines; simplifies PCB routing vs. SPI/I²C DCPs |
Pinout & Package
ISL90460TIE527Z-TK is packaged in a 5-lead SC-70 (P5.049) surface-mount package, measuring 2.15mm × 1.35mm × 0.95mm, with gull-wing leads and RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply voltage input | Power rail connection (2.7–5.5V); must be decoupled locally for noise-sensitive analog use |
| GND | Ground reference | Return path for wiper current and digital logic; shared with RH terminal's low-side node |
| U/D | Direction control input | High = increment wiper; Low = decrement wiper; edge-triggered only when CS is asserted |
| CS | Chip select input | Active-low enable; latches current wiper position on rising edge; places device in standby when high |
| RH | Wiper/High terminal | Variable resistance output (RH-to-GND); connects to one end of resistor array and wiper switch network |
Key Features
| Feature | Design Value |
|---|---|
| Volatile XDCP architecture | Eliminates EEPROM wear-out concerns and write-cycle delays; ideal for dynamic real-time calibration |
| 2-pin UP/DN interface | Reduces GPIO count and PCB trace count vs. serial-interface potentiometers; simplifies microcontroller integration |
| Low 0.3µA standby current | Enables use in battery-powered sensor nodes where quiescent power dominates lifetime budget |
| 35ppm/°C tempco | Provides predictable resistance drift across industrial temperature range, critical for precision transducer signal chains |
| SC-70 package | Supports high-density layouts in space-constrained applications like portable medical devices and compact IoT sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled rheostat applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL90460TIH527Z-TK | SOT-23-5 package (vs. SC-70); identical electrical specs and pinout mapping | Requires different land pattern and reflow profile; same functional behavior in circuit | Select when SOT-23 footprint is standardized in existing layout or preferred for handling robustness |
| ISL23511IRUZ-TK | Non-volatile EEPROM storage; 64-tap resolution; 50kΩ RTOTAL; same SC-70 package | Retains wiper setting through power cycles; suited for systems requiring persistent calibration | Choose when power-loss immunity is mandatory and higher resolution justifies cost premium |
Compared with ISL90460TIE527Z-TK, ISL90460TIH527Z-TK offers identical functionality in a mechanically distinct SOT-23 package, while ISL23511IRUZ-TK adds non-volatility and finer resolution at the cost of EEPROM endurance limits and higher supply current.

FAQ
What is the end-to-end resistance value of the ISL90460TIE527Z-TK?
The ISL90460TIE527Z-TK has an RTOTAL of 100kΩ, measured between the RH terminal and GND. This value is fixed for this variant and defines the maximum resistance achievable in its rheostat configuration. It is specified with ±20% tolerance (80kΩ to 120kΩ) over temperature and process variation.
Does the ISL90460TIE527Z-TK retain wiper position after power cycling?
No, the ISL90460TIE527Z-TK uses volatile memory and resets to the default wiper position (typically mid-scale or last powered state depending on internal reset behavior) upon power-up. It does not include EEPROM or non-volatile storage, so external circuitry or host MCU initialization is required to restore desired settings.
What package type is used for the ISL90460TIE527Z-TK?
The ISL90460TIE527Z-TK is supplied in a 5-lead SC-70 package (P5.049), with dimensions 2.15mm × 1.35mm × 0.95mm. This RoHS-compliant, lead-free package features gull-wing leads and is distinct from the SOT-23 variant (ISL90460TIH527Z-TK) despite identical pinout and electrical function.
Can the ISL90460TIE527Z-TK be used as a three-terminal potentiometer?
No, the ISL90460TIE527Z-TK is internally configured exclusively as a two-terminal rheostat (RH-to-GND). The RL terminal is permanently tied to GND and not brought out to a pin. It cannot function as a traditional three-terminal potentiometer with independent high/low/wiper terminals.
What is the maximum toggle rate supported by the ISL90460TIE527Z-TK's Up/Down interface?
The ISL90460TIE527Z-TK supports an Up/Down toggle rate of up to 1MHz, with minimum U/D HIGH and LOW periods of 300ns each. This allows rapid wiper positioning-e.g., full 32-step traversal in under 32µs-making it suitable for dynamic calibration loops requiring sub-millisecond response.
