DS1100LU-500+

P1-P3P4-P6P7-P7
1 of 7
GENERAL DESCRIPTION
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.
Maxim can customize standard products to meet
special needs.

NOTES:
1) Initial tolerances are ± with respect to the nominal value at +25°C and V
CC
= 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
custom.oscillators@maxim-ic.com.
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 I
CC
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 parameter for TAP 1. Delay values for TAP 2 to TAP 5 meet data sheet
specifications.
