MAXIM DS1088L Technical data
General Description
The DS1088L is a low-cost clock generator that produces a square-wave output without external timing
components. The fixed-frequency oscillator is available
in factory-calibrated frequencies from 312kHz to
133MHz. The DS1088L has a power-down pin for
power-sensitive applications.

ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
(TA= -20°C to +85°C)
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 indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
