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.
