DESCRIPTION  
The DS1040 Pulse Generator is a user-programmable one-shot with a choice of five precise pulse widths.  
Maximum widths range from 50 ns to 500 ns; increments range from 2.5 ns to 100 ns. For maximum  
flexibility in applications such as magneto-optical read/write disk laser power control, varieties are  
offered with equal and unequal increments. The DS1040 is offered in standard 8-pin DIPs and 8-pin  
mini-SOICs. Low cost and superior reliability over hybrid technology are achieved by the combination  
of a 100% CMOS silicon design and industry standard packaging. The DS1040 series of pulse generators  
provide a nominal width accuracy of ±5% or ±2 ns, whichever is greater. In response to the rising edge  
of the input (trigger) pulse, the DS1040 produces an output pulse with a width determined by the logic  
states of the three parallel programming pins. For convenience, both inverting and non-inverting outputs  
are supplied. The intrinsic delay between the trigger pulse and the output pulse is no more than 10 ns.  
Each output is capable of driving up to five 74LS loads.  
Dallas Semiconductor can customize standard products to meet special needs. For special request and  
rapid delivery, call (972) 371–4348.
