Pin Descriptions

Host Interface Pins

Serial Clock (SCL)

The SCL input is used to clock data into and out of the

X9241A.

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 values, refer to the guidelines

for calculating typical values on the bus pull-up resistors

graph.

Address

The Address inputs are used to set the least significant 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 X9241A.

Potentiometer Pins

connections on either end of a mechanical potentiometer.

The wiper outputs are equivalent to the wiper output of a

mechanical potentiometer.

*Add "T1" suffix for tape and reel.

**Add “T2” suffix for tape and reel.

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.

***Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
