说明 Specifically designed for use in low-power systems, the DS1033 has three independent, buffered delays that reproduce logic inputs after delays ranging from 8ns to 30ns at each output. Characterized for operating over the 2.7V to 3.6V range, nominal tolerance is ±1.5ns with additional tolerance of ±1.0ns over temperature and voltage for faster delays (see table). Both leading- and trailing-edge accuracy are specified. Each output can drive up to ten 74LS loads.
The DS1033 brings the benefits of an all-silicon delay circuit to new low-voltage systems. Dallas delay lines provide an effective, economical solution to the designer working with the complex timing requirements of mismatched ASICs or other components, or with the strict timing tolerances of increasing system clock rates. Besides fine-tuning system timing, the DS1033 can also function as a pulse width modulator or free-running oscillator. Innovative circuit designs and factory laser or EPROM trimming enhance accuracy without the need for external components, saving cost and space.
