*Add "T1" suffix for tape and reel.
**Add “T2” suffix for tape and reel.
***Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
NOTE: 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.
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
V_H/R_H(V_H0/R_H0 TO V_H3/R_H3), V_L/R_L (V_L0/R_L0 TO V_L3/R_L3)
The R_H and R_L inputs are equivalent to the terminal
connections on either end of a mechanical potentiometer.
V_W/R_W (V_W0/R_W0 TO V_W3/R_W3)
The wiper outputs are equivalent to the wiper output of a
mechanical potentiometer.
