Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
*Add "T1" suffix for tape and reel.
Pin Descriptions
V
The high (V
equivalent to the fixed terminals of a mechanical
potentiometer. The minimum voltage is –5V and the
maximum is +5V. It should be noted that the terminology of
V
relation to wiper movement direction selected by the U/D
input and not the voltage potential on the terminal.
V
V
of a mechanical potentiometer. The position of the wiper
within the array is determined by the control inputs. The
wiper terminal series resistance is typically 40Ω.
Up/Down (U/D)
The U/D input controls the direction of the wiper movement
and whether the counter is incriminated or decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC will
move the wiper and either increment or decrement the
counter in the direction indicated by the logic level on the
U/D input.
Chip Select (CS)
The device is selected when the CS input is LOW. The
current counter value is stored in nonvolatile memory when
CS is returned HIGH while the INC input is also HIGH. After
the store operation is complete the device will be placed in
the low power standby mode until the device is selected
once again.
