DESCRIPTION

The DS1010 series delay line has ten equally spaced taps providing delays from 5 ns to 500 ns. The
devices are offered in a standard 14-pin DIP which is pin-compatible with hybrid delay lines.
Alternatively, a 16-pin SOIC is available for surface mount technology which reduces PC board area.
Since the DS1010 is an all-silicon solution, better economy is achieved when compared to older methods
using hybrid techniques. The DS1010 series delay lines provide a nominal accuracy of ±5% or ±2 ns,
whichever is greater. The DS1010 reproduces the input logic state at the TAP 10 output after a fixed
delay as specified by the dash number extension of the part number. The DS1010 is desi gned to produce
both leading and trailing edge with equal precision. Each tap is capable of driving up to 10 74LS type
loads. Dallas Semiconductor can customize standard products to meet special needs. For special requests

= 5V @ 25°C. Input-to-tap delays accurate on both rising and falling edges within ±2 ns or ±5%

whichever is greater.

4. See “Test Conditions” section.

5. For DS1010 delay lines with a TAP 10 delay of 100 ns or greater, tempe rature variations from 25°C
to 0°C or 70°C may produce an additional input-to-tap delay shift of ±2ns or ±3%, whichever is
greater.

6. For DS1010 delay lines with a TAP 10 delay less than 100 ns, temperature variations from 25°C to
0°C or 70°C may produce an additional input-to-tap delay shift of ±1 ns or ±9%, whichever is greater.

7. All tap delays tend to vary unidirectionally with temperature or volta ge changes. For example, if TAP
1 slows down, all other taps will also slow down; TAP 3 can never be faster than TAP 2.

8. Pulse width and period specifications may be exceeded; however, accuracy will be application­sensitive (decoupling, layout, etc.).

9. Certain high-frequency applications not recommended for -50 in 16-pin package. Consult factory.

TEST SETUP DESCRIPTION

Figure 3 illustrates the hardware configuration used for measuring the timing parameters on the DS1010.
The input waveform is produced by a precision pulse generator under software control. Time delays are
measured by a time interval counter (20 ps resolution) connected between the input and each tap. Each
tap is selected and connected to the counter by a VHF switch control unit. All measurements are fully
automated, with each instrument controlled by a central computer over an IEEE 488 bus.

TEST CONDITIONS
INPUT:

Ambient Temperature: 25°C ± 3°C
Supply Voltage (VCC): 5.0V ± 0.1V
Input Pulse: High = 3.0V ± 0.1V

Low = 0.0V ± 0.1V
Source Impedance: 50 ohm max.
Rise and Fall Time: 3.0 ns max.
Pulse Width: 500 ns (1 µs for -500)
Period: 1 µs ( 2 µs for -500)

OUTPUT:

Each output is loaded with the equivalent of one 74FO4 input gate. Dela y is measured at the 1.5V level
on the rising and falling edge.

Above conditions are for test only and do not restrict the operation of the device under other data sheet
conditions.
