DESCRIPTION
The DS1040 Pulse Generator is a user-programmable
one-shot with a choice of five precise pulse widths. Max-
imum 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 la-
ser 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 indus-
try 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 con-
venience, 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.

ucts to meet special needs. For special request and rap-
