X9317TP

Digital Potentiometers Overview

The X9317TP is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single channel with 100 tap points and a total end-to-end resistance of 100 kOhms. The device utilizes a nonvolatile memory to store the wiper position, allowing it to recall settings upon power-up. It operates on a 5V supply and employs an Up/Down (U/D, INC, CS) serial interface for control. The component is housed in an 8-PDIP package and is designed for through-hole mounting.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position data for 100 years
• Linear taper with 100 resistive element taps
• 3-wire serial interface (Up/Down, Increment, Chip Select)
• End-to-end resistance tolerance of ±20%

Digital Potentiometers Applications

• Voltage control circuits requiring programmable resistance
• Current control applications using variable resistor mode
• System calibration where power-on state retention is required

Digital Potentiometers Part Context

The X9317TP belongs to the X9317 series of XDCP devices. This specific part number denotes the 100 kOhm variant packaged in an 8-pin PDIP format. It is distinct from surface-mount variants such as the X9317UV8IZ which uses a TSSOP-8 package. The series generally offers low standby current and high reliability endurance.

Digital Potentiometers Replacement Considerations

The X9317TP is marked as obsolete and no longer manufactured. A confirmed public substitute is the DS1804-100+ by Analog Devices Inc./Maxim Integrated. Designers should verify pin compatibility and electrical specifications when transitioning to alternative components.
