Except for ‘‘Operating Temperature Range’’ they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation. Note 2: Unless otherwise specified min/max limits apply across the 0 §Ct o7 0 §C range for the DS0025C. Note 3: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown as max or min on absolute value basis. Note 4: Parameter values apply for clock pulse width determined by input pulse width. Note 5: Parameter values for input width greater than output clock pulse width. Timing Diagram Input waveform: PRR e 0.5 MHz VP-P e 5.0V tr e tf s 10 ns Pulse width: A. 1.0 ms B. 200 ns TL/F/5852–5
