PIN DESCRIPTIONS

VH and VL

The high (VH) and low (VL) terminals of the X9511 are

equivalent to the ﬁxed terminals of a mechanical potenti-

ometer. The minimum voltage is –5V and the maximum

is +5V. It should be noted that the terminology of VL and

VH references the relative position of the terminal in rela-

tion to wiper movement direction selected by the PU and

PD inputs and not the voltage potential on the terminal.

The debounced PU input is for incrementing the wiper

position. An on-chip pull-up holds the PU input HIGH. A

switch closure to ground or a LOW logic level will, after a

debounce time, move the wiper to the next adjacent

higher tap position.

The debounced PD input is for decrementing the wiper

position. An on-chip pull-up holds the PD input HIGH. A

switch closure to ground or a LOW logic level will, after a

debounce time, move the wiper to the next adjacent

lower tap position.

ASE

The debounced ASE (AUTOSTORE enable) pin can be

in one of two states:

VIL – Autostore is enabled. When VCC powers-down an

automatic store cycle takes place.

VIH – AUTOSTORE is disabled. A LOW to HIGH will ini-

tiate 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 X9511 will store the current wiper

position to the E2PROM.
