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.

PIN CONFIGURATION
PIN NAMES
PRINCIPLES OF OPERATION
The X9241A is a highly integrated microcircuit
incorporating four resistor arrays, their associated
registers and counters and the serial interface logic
providing direct communication between the host and
the XDCP potentiometers.
