a. The PCT2303N chipset specifications are guaranteed when the typical application circuit (including component
tolerance) and any PCT303A and PCT303L are used.
b. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions.
Typical values apply at nominal supply voltages and an operating temperature of 25°C unless otherwise stated.
c. The digital supply, VD, can operate from either 3.3V or 5.0V. The PCT303A supports interface to 3.3V logic when
operating from 3.3V. The 3.3V operation applies to both the serial port and the digital signals RESET, ID0, and ID1.
Absolute Maximum Ratings
Permanent device damage may occur if the absolute maximum ratings are exceeded. Functional operation should
be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
