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_H /R_H and V_L /R_L
The high (V_H/R_H) and low (V_L/R_L) terminals of the X9116
are equivalent to the fixed terminals of a mechanical
potentiometer. The minimum voltage is V_SS and the
maximum is V_CC.
V_W/R_W
R_w/R_w is the wiper terminal and is equivalent to the movable
terminal 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 200Ω to
400Ω depending upon V_CC.
Up/Down (U/D)
The U/D input controls the direction of the wiper movement
and whether the counter is incremented (up) or decremented
(down).
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 X9116 will be placed in
the low power standby mode until the device is selected
once again.
