DESCRIPTION
The DS1045 is a programmable silicon delay line having one input and two 4-bit programmable delay
outputs. Each 4-bit programmable output offers the user 16 possible delay values to select from, starting
with a minimum inherent DS1045 delay of 9ns and a maximum achievable delay in the standard DS1045
family of 84ns. The standard DS1045 product line provides the user with three devices having uniform
delay increments of 3ns, 4ns, and 5ns, depending on the device. Table 1 presents standard device family
and delay capability. Additionally, custom delay increments are available for special order through Dallas
Semiconductor.
The DS1045 is TTL and CMOS-compatible and capable 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 surface mount 16-pin SOIC package.
