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 b55§Ct o a125§C temperature range for the DS1649 and DS1679 and across the 0 §Ct o a70§C range for the DS3649 and DS3679. All typical values are for T A e 25§C and V CC e 5V. 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: When measuring output drive current and switching response for the DS1679 and DS3679 a 15 X resistor should be placed in series with each output. This resistor is internal to the DS1649/DS3649 and need not be added. AC Test Circuits and Switching Time Waveforms tSg,t S’,t R,t F TL/F/7515–4 TL/F/7515–5 FIGURE 1
