DS1100L
3.3V 5-Tap Economy Timing Element (Delay Line)
GENERAL DESCRIPTION
FEATURES
The DS1100L is a 3.3V version of the DS1100. It
is characterized for operation over the range 3.0V
to 3.6V. The DS1100L series delay lines have
five equally spaced taps providing delays from
4ns to 500ns. These devices are offered in
surface-mount packages to save PCB area. Low
cost and superior reliability over hybrid
technology is achieved by the combination of a
100% silicon delay line and industry-standard
µMAX® and SO packaging. The DS1100L 5-tap
silicon delay line reproduces the input-logic state
at the output after a fixed delay as specified by
the extension of the part number after the dash.
The DS1100L is designed to reproduce both
leading and trailing edges with equal precision.
Each tap is capable of driving up to 10 74LS
loads.

NOTES
1) Initial tolerances are ± with respect to the nominal value at +25°C and VCC = 3.3V for both leading and
trailing edge.
2) Temperature and voltage tolerance is with respect to the nominal delay value over the stated temperature
range, and a supply-voltage range of 3.0V to 3.6V.
3) All tap delays tend to vary unidirectionally with temperature or voltage changes. For example, if TAP 1
slows down, all other taps also slow down; TAP 3 can never be faster than TAP 2.
4) Intermediate delay values are available on a custom basis. For further information, contact the factory at
[email protected]
5) All voltages are referenced to ground.
6) Measured with outputs open.
7) See Test Conditions section at the end of this data sheet.
8) Frequencies higher than 1MHz result in higher ICC values.
9) At or near maximum frequency the delay accuracy can vary and will be application sensitive (i.e.,
decoupling, layout).
10) The “-75” version is specified and tested with an additional 2ns of tolerance on the specified minimum
input-to-tap delay tolerance parameters for TAP 1 to TAP 3. Delay values for TAP 4 to TAP 5 meet data
sheet specifications.

TERMINOLOGY
Period: The time elapsed between the leading edge of the first pulse and the leading edge of the
following pulse.
tWI (Pulse Width): The elapsed time on the pulse between the 1.5V point on the leading edge and the
1.5V point on the trailing edge or the 1.5V point on the trailing edge and the 1.5V point on the leading
edge.
tRISE (Input Rise Time): The elapsed time between the 20% and the 80% point on the leading edge of the
input pulse.
tFALL (Input Fall Time): The elapsed time between the 80% and the 20% point on the trailing edge of the
input pulse.
tPLH (Time Delay, Rising): The elapsed time between the 1.5V point on the leading edge of the input
pulse and the 1.5V point on the leading edge of any tap output pulse.
tPHL (Time Delay, Falling): The elapsed time between the 1.5V point on the trailing edge of the input
pulse and the 1.5V point on the trailing edge of any tap output pulse.
TEST SETUP DESCRIPTION
Figure 3 illustrates the hardware configuration used for measuring the timing parameters on the
DS1100L. The input waveform is produced by a precision pulse generator under software control. Time
delays are measured by a time interval counter (20ps 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.

OUTPUT:
Each output is loaded with the equivalent of one 74F04 input gate. Delay is measured at the 1.5V level on
the rising and falling edge.

data sheet conditions.
