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.
PIN DESCRIPTIONS
Potentiometer Pins
Host Interface Pins
Serial Clock (SCL)
The SCL input is used to clock data into and out of the
X9221A.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into
and out of the device. It is an open drain output and
may be wire-ORed with any number of open drain or
open collector outputs. An open drain output requires
the use of a pull-up resistor. For selecting typical val-
ues, refer to the guidelines for calculating typical val-
ues on the bus pull-up resistors graph.
Address
The Address inputs are used to set the least signifi-
cant 4 bits of the 8-bit slave address. A match in the
slave address serial data stream must be made with
the Address input in order to initiate communication
with the X9221A
V_H/R_H(V_H0/R_H0-V_H1/R_H1), V_L/R_L (V_L0/R_L0-V_L1/R_L1)
The V_H/R_H and V_L/R_L inputs are equivalent to the ter-
minal connections on either end of a mechanical
potentiometer.
V_W/R_W (V_W0/R_W0-V_W1/R_W1)
The wiper outputs are equivalent to the wiper output of
a mechanical potentiometer.
