DS1045

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 9 ns and a maximum achievable delay in the standard DS1045 family of 84 ns. The standard DS1045 product line provides the user with three devices having uniform delay increments of 3, 4, and 5 ns, 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.
