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

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

Potentiometer Pins

minal connections on either end of a mechanical

potentiometer.

The wiper outputs are equivalent to the wiper output of

a mechanical potentiometer.
