NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is 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.
2. Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
Pin Descriptions

The high (V
H
) and low (V
L
) terminals of the device are
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
L
and V
H
references the relative position of the terminal in
relation to wiper movement direction selected by the U/D
input and not the voltage potential on the terminal.
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.

is the wiper terminal, 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 40Ω.
Up/Down (U/D)
The U/D input controls the direction of the wiper movement
and whether the counter is incremented 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.
