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 space-saving surface-mount 16-pin SO package.

Key Features
  • All-silicon time delay
  • Two programmable outputs from a single input produce output-to-output delays between 9ns and 84ns depending on device type
  • Programmable via four input pins
  • Programmable increments of 3ns to 5ns with a minimum of 9ns and a maximum of 84ns
  • Output pulse is a reproduction of input pulse after
  • Delay with both leading and trailing edge accuracy
  • Surface mount 16-pin SOIC
  • Auto-insertable
  • Low-power CMOS design is TTL-compatible
