DESCRIPTION
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.
The position of the wiper can be automatically stored in E2
memory and then be recalled upon a subsequent power-
on operation.
All Xicor nonvolatile products are designed and tested
for applications requiring extended endurance and data
retention.
