303DL Electrical Characteristics
303DL Recommended Operating Conditions
Table 17 303DL Recommended Operating Conditions
303DL 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.

The 303DL specifications are guaranteed when the typical application circuit (including component tolerance) and
any PCT303D and PCT303L are used. See Figure 2 on page 6 for a typical application circuit.
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.
The digital supply, V
D
, can operate from either 3.3V or 5.0V. The PCT303D 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 RGDT, OFHK, and
RESET, M0, and M1.
