CAT5114YI-00-T3

Digital Potentiometers Overview

The CAT5114YI-00-T3 is a single 32-tap digitally programmable potentiometer from onsemi, featuring nonvolatile EEPROM storage. It operates within a supply voltage range of 2.5 V to 6.0 V and utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. The device offers a resistance value of 100 kOhms with ±20% tolerance and a linear taper. Packaged in a TSSOP-8 format, it supports industrial operating temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile EEPROM wiper storage retains settings during power loss
• Single supply operation from 2.5 V to 6.0 V
• Increment/Up-Down serial control interface (CS, U/D, INC)
• 32-position linear taper potentiometer with 100 kOhm resistance

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Contrast, brightness, and volume controls

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'T3' confirms tape and reel packaging containing 3,000 units per reel. Confirm the 'Y' package code corresponds to the TSSOP-8 form factor and the '00' resistance code indicates the 100 kOhm variant. Ensure the 'I' temperature grade matches the required industrial range of -40°C to +85°C for the target application environment.

Digital Potentiometers Selection Notes

Select this component when a nonvolatile digital potentiometer with high resistance (100 kOhms) and simple serial control is required. The TSSOP-8 package suits space-constrained surface-mount designs. Verify that the 32 tap resolution meets the system's adjustment granularity needs and that the 2.5 V to 6.0 V supply range aligns with the circuit's power rails.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digitally programmable potentiometers. The YI-00-T3 designation specifies the TSSOP-8 package, Industrial temperature rating, 100 kOhm resistance, and Tape & Reel delivery method. It serves as an electronic replacement for mechanical pots in automated production lines or remote adjustment scenarios.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same series include CAT5114VI-00-GT3 (SOIC-8) and CAT5114ZI-00-GT3 (MSOP-8). For different resistance values, use CAT5114YI-10-T3 (10 kOhms) or CAT5114YI-50-T3 (50 kOhms). Ensure any substitute maintains the nonvolatile memory feature and Up/Down interface.
