Note:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under
Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended
periods of time may affect device reliability.

Note: 1. Timing is based on the XC3142A, for other devices see timing calculator.
The use of two pull-up resistors per longline, available on other XC3000 devices, is not a valid design option for XC3100A
devices.
