DESCRIPTION
In its most simple configuration, the DS1012 2-in-1
Sub-Miniature Silicon Delay Line Chip provides two in-
puts, each of which in turn provides independent delays
to a pair of outputs. The DS1012-1 and DS1012-3 are
examples of catalog parts having this basic configura-
tion. Any of the four outputs can be inverted at the time
of manufacture.
For applications requiring two-input timed logic func-
tions, at the time of manufacture the simple delay on
OUT4 can be replaced by one of the following: OR,
NOR, XOR, or XNOR. Similarly, a timed AND, NAND,
HALF-XOR (D3 AND D4), or NOT HALF-XOR (D3 OR
D4) can be substituted for the simple delay on OUT3.
DS1012-2, DS1012-4, and DS1012-5 are examples of
catalog parts configured with logic functions on OUT3
and OUT4. Note that DS1012-2 also utilizes an output
inversion on OUT2.
In any configuration, delays D1 (t
D1
) and D2 (t
D2
) can be
specified within the range of ~3 ns to 10 ns. Delays D3
(t
D3
) and D4 (t
D4
) can be specified to have values be-
tween ~3 ns and 40 ns. The worst case leading edge
delay accuracy at nominal voltage and room tempera-
ture is
±2
ns. The DS1012 is offered in two packages: an
8-pin DIP and an 8-pin 150 mil wide mini-SOIC.
Dallas Semiconductor offers the DS1012 in a wide vari-
ety of custom delay and logic configurations. For special
