1 / 6 page 1 of 6 071700 FEATURES All-silicon time delay Two programmable outputs from a single input produce output-to-output delays between 9 and 84 ns depending on device type Programmable via four input pins Programmable increments of 3 to 5 ns with a minimum 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 PIN ASSIGNMENT PIN DESCRIPTION IN - Delay Line Input OUTA, OUTB - Delay Line Outputs A0-A3 - Parallel Program Inputs for OUT1 B0-B3 - Parallel Program Inputs for OUT2 EA , EB - Enable A and B Inputs VCC - +5V Input GND - Ground 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 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.
