... The Xicor X9514 is a push button controlled, logarithmic taper potentiometer and is ideal for push button con- trolled resistance trimming. The X9514 is a resistor array composed of 31 resistive elements. Between each element and at either end are tap points accessible to the wiper element. The position of the wiper element is controlled by the PU and PD inputs ...

... V – AUTOSTORE is disabled. A LOW to HIGH will IH initiate a manual store operation. This is for a user who wishes to connect a push button switch to this pin. For every valid push, the X9514 will store the current wiper position to the E 2 PROM. Typical Attenuation Characteristics (dB) 0 ...

... At either end of the array and between each resistor is an electronic switch that trans- fers the potential at that point to the wiper. The X9514 is designed to interface directly to two push button switches for effectively moving the wiper up or down. The PU and PD inputs increment or decrement a 5-bit counter respectively ...
