Product details
Overview
DS1100LU-50+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 10ns (TAP 1), 20ns (TAP 2), 30ns (TAP 3), 40ns (TAP 4), and 50ns (TAP 5), operating over -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin µMAX package for high-density PCB layouts.
For engineers reviewing the DS1100LU-50+ datasheet, DS1100LU-50+ pinout, DS1100LU-50+ application, or DS1100LU-50+ equivalent, this page delivers verified timing accuracy, edge-preserving delay behavior, TTL/CMOS compatibility, and industrial-temperature operation-key selection criteria for digital synchronization, pulse shaping, and signal alignment circuits.
Technical Context
The DS1100LU-50+ implements a monolithic all-silicon delay architecture that reproduces both leading and trailing edges with equal precision at fixed intervals, eliminating phase skew between taps. Its five equally spaced outputs are calibrated to ±2ns tolerance (for ≤40ns delays) at +25°C/3.3V and ±4ns across -40°C to +85°C.
Each tap operates with low-power CMOS logic, supports 3.0V–3.6V supply, exhibits 5–10pF input capacitance, and delivers sub-2.5ns rise/fall times-enabling reliable use in high-speed digital systems where deterministic propagation delay and minimal jitter are required.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50+ | Same delay values and electrical specs, but in 8-pin SO (150-mil) package instead of µMAX | Better suited for through-hole prototyping or manual rework; larger footprint reduces board density | Select DS1100LZ-50+ when SO packaging simplifies assembly or thermal management is less constrained |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 3.3V PECL interface, ±100ps typical delay accuracy, higher speed (up to 3GHz), but requires negative bias and differential signaling | Targeted at RF and high-frequency serial links-not drop-in for single-ended TTL/CMOS systems | Choose MC100EP195MNR4G only when PECL signaling, sub-100ps jitter, or >1GHz bandwidth is required |
Compared with DS1100LZ-50+, the DS1100LU-50+ offers identical timing performance in a 3×3mm µMAX package-ideal for miniaturized designs-while the MC100EP195MNR4G serves ultra-high-speed applications requiring differential PECL I/O and tighter delay tolerance, but demands different power and layout infrastructure.

FAQ
What is the maximum operating frequency supported by DS1100LU-50+?
The DS1100LU-50+ does not specify a maximum operating frequency, but its AC characteristics-including 2.0–2.5ns rise/fall times and 200μs power-up time-support reliable operation with input periods down to 1μs (1MHz). At higher frequencies, delay accuracy degrades due to layout sensitivity and decoupling; for stable 50ns staging, inputs should remain below 50MHz to maintain edge fidelity and minimize jitter-induced uncertainty in the DS1100LU-50+ output timing.
Does DS1100LU-50+ require external termination resistors?
No, the DS1100LU-50+ does not require external termination resistors. Its outputs are designed to drive up to 10 LS-TTL loads directly, with specified VOH/VOL levels and current drive capability (IOH = –1mA, IOL = 8mA) under 3.0V–3.6V supply. Termination is only needed if interfacing with high-impedance or transmission-line-coupled loads beyond standard logic gates-otherwise, proper local VCC decoupling (0.1µF ceramic) suffices for stable DS1100LU-50+ operation.
How does DS1100LU-50+ handle temperature-induced delay drift?
The DS1100LU-50+ exhibits unidirectional delay drift with temperature: all taps slow down or speed up together, preserving relative spacing. Over –40°C to +85°C, delay tolerance is ±4ns for taps ≤40ns (e.g., TAP1–TAP4), and ±13% for TAP5 (50ns). This behavior is documented in Table 1 and Note 3 of the datasheet-ensuring that inter-tap skew remains near zero, which is essential for maintaining signal alignment integrity in the DS1100LU-50+ across thermal cycling.
Can DS1100LU-50+ be used with 5V logic systems?
No, DS1100LU-50+ is strictly a 3.3V device with absolute maximum input voltage of +6.0V, but its VIH threshold is specified at ≥2.0V and VIL ≤0.8V under 3.0–3.6V supply. Direct connection to 5V logic violates the input voltage rating and risks latch-up or accelerated wear. To interface with 5V systems, level translation (e.g., TXB0108 or discrete resistor divider) is required before applying signals to the DS1100LU-50+ IN pin-never apply 5V directly to DS1100LU-50+.
Is the DS1100LU-50+ pinout compatible with other DS1100L variants?
Yes, all DS1100L variants-including DS1100LU-50+, DS1100LU-100+, and DS1100LZ-50+-share identical 8-pin functional pinout (IN, TAP1–TAP5, VCC, GND), regardless of package (µMAX vs. SO) or delay value. The pin assignment diagram confirms consistent mapping across the family, enabling layout reuse when scaling delay ranges or changing packages-though mechanical footprint and thermal pad requirements differ between DS1100LU-50+ (U8+1) and DS1100LZ-50+ (S8+4).
