Bit Dual Programmable Delay Line
DS1045
021798 1/6
FEATURES
All–silicon time delay
Two programmable outputs from a single input pro-
duce output–to–output delays between 9 and 84 ns
depending on device type
Programmable via four input pins
Programmable increments of 2 to 5 ns with a mini-
mum of 9 ns and a maximum of 84 ns
Output pulse is a reproduction of input pulse after
delay with both leading and trailing edge accuracy
Standard 16–pin DIP or surface mount 16–pin SOIC
Auto–insertable
Low–power CMOS design is TTL–compatible

DESCRIPTION
The DS1045 is a programmable silicon delay line hav-
ing one input and two 4–bit programmable delay out-
puts. Each 4–bit programmable output offers the user
16 possible delay values to select from, starting with a
minimum inherent DS1045 delay of 9 ns and a maxi-
mum achievable delay in the standard DS1045 family of
84 ns. The standard DS1045 product line provides the
user with four devices having uniform delay increments of
2, 3, 4, and 5 ns depending on the device. Table 1 pres-
ents standard device family and delay capability. Addi-
tionally, custom delay increments are available for spe-
cial order through Dallas Semiconductor.
The DS1045 is TTL and CMOS–compatible and capa-
ble of driving ten 74LS–type loads. The output produced
by the DS1045 is both rising and falling edge precise.
The DS1045 programmable silicon delay line has been
designed as a reliable, economic alternative to hybrid
programmable delay lines. It is offered in a standard
16–pin auto–insertable DIP and a space–saving sur-
face mount 16–pin SOIC package.
