Product details
Overview
DS1100LU-20/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line in an 8-pin µMAX package, delivering precise fixed delays of 4ns, 8ns, 12ns, 16ns, and 20ns across taps. It reproduces both leading and trailing edges with ±2ns tolerance at +25°C/3.3V and drives up to 10 LS-TTL loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment in industrial control and test equipment.
For engineers reviewing the DS1100LU-20/T&R datasheet, DS1100LU-20/T&R pinout, DS1100LU-20/T&R application, or DS1100LU-20/T&R equivalent, key selection criteria include tap delay accuracy over -40°C to +85°C, 3.3V CMOS/TTL compatibility, µMAX footprint constraints, and guaranteed edge fidelity for synchronous signal conditioning.
Technical Context
The DS1100LU-20/T&R implements a monolithic all-silicon delay architecture-no hybrid or ceramic components-with five equally spaced output taps derived from a single input signal path. Each tap provides deterministic propagation delay without jitter accumulation or phase drift.
It operates across 3.0V–3.6V supply and supports full industrial temperature range (-40°C to +85°C), with delay tolerances specified as ±2ns (≤40ns delays) or ±5% (>40ns delays), referenced to nominal values at +25°C/3.3V and tracking unidirectionally with voltage/temperature changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail tolerance |
| Nominal Tap Delays | 4ns / 8ns / 12ns / 16ns / 20ns - fixed, equally spaced delays enabling precise multi-point timing alignment |
| Delay Tolerance | ±2ns at +25°C/3.3V - guarantees sub-nanosecond edge placement repeatability for critical setup/hold windows |
| Input Compatibility | TTL- and CMOS-compatible - accepts 0.8V/2.0V logic thresholds without level-shifting circuitry |
| Output Drive | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS loads without buffering |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded timing applications without derating |
Pinout & Package
DS1100LU-20/T&R uses the 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), optimized for high-density PCB layouts and compatible with vapor-phase and IR reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS levels; triggers all five delay paths simultaneously |
| 2 | TAP 2 | Second delayed output (8ns); electrically identical to other taps, rated for 10 LS-TTL loads |
| 3 | TAP 4 | Fourth delayed output (16ns); shares same drive strength and edge fidelity as TAP 2 and TAP 5 |
| 4 | GND | Analog/digital ground reference; must be low-impedance for delay stability and noise immunity |
| 5 | TAP 5 | Fifth delayed output (20ns); maximum delay tap, fully characterized for rise/fall time (2.0–2.5ns) |
| 6 | TAP 3 | Third delayed output (12ns); center tap used for symmetrical delay interpolation or feedback timing |
| 7 | TAP 1 | First delayed output (4ns); shortest delay tap, validated for minimal pulse distortion and duty-cycle preservation |
| 8 | VCC | +3.3V supply pin; requires local 0.1µF ceramic decoupling adjacent to pin for AC noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid component aging and thermal hysteresis, ensuring long-term delay stability over 10+ years |
| Equal-edge precision | Simultaneous leading- and trailing-edge delay matching enables accurate pulse-width preservation in timing-critical paths |
| 5-tap parallel outputs | Provides five discrete, non-multiplexed delay points from one input-no sequencing or control logic required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-20/T&R | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB footprint (4.9mm × 3.9mm vs. 3.0mm × 3.0mm); less suitable for space-constrained designs | Select when legacy SO-8 assembly infrastructure exists or thermal dissipation >362mW is needed |
| ON Semiconductor MC100EP195DG | 5-tap ECL delay line with 3.3V PECL interface; ±15ps typical jitter vs. DS1100LU-20/T&R's ±2ns absolute delay error | Targets ultra-low-jitter clock distribution, not general-purpose logic delay; requires negative supply and level translation | Select only for sub-100ps timing integrity needs where ECL infrastructure is already deployed |
Compared with DS1100LZ-20/T&R and MC100EP195DG, DS1100LU-20/T&R uniquely balances compact µMAX packaging, industrial temperature support, and TTL/CMOS interoperability-making it optimal for cost-sensitive, space-constrained embedded timing where absolute delay accuracy matters more than picosecond jitter.

FAQ
What is the exact delay value for each tap of the DS1100LU-20/T&R?
The DS1100LU-20/T&R provides five fixed, equally spaced delays: TAP 1 = 4ns, TAP 2 = 8ns, TAP 3 = 12ns, TAP 4 = 16ns, and TAP 5 = 20ns, all measured at the 1.5V logic threshold under VCC = 3.3V and TA = +25°C. These values are guaranteed across the full -40°C to +85°C operating range with specified tolerances.
Does the DS1100LU-20/T&R require external configuration or programming?
No, the DS1100LU-20/T&R is a passive, fixed-function delay line with no configuration pins, registers, or serial interface. All five tap delays are hardwired in silicon and become active immediately upon power-up with no initialization sequence required. The DS1100LU-20/T&R operates as soon as VCC reaches valid logic levels.
Can the DS1100LU-20/T&R drive standard logic families directly?
Yes, the DS1100LU-20/T&R can directly drive up to 10 LS-TTL loads per tap, and its outputs are TTL- and CMOS-compatible with VIH ≥ 2.0V and VIL ≤ 0.8V. No level-shifting or buffer circuitry is needed when interfacing with 74LS, 74HC, or modern 3.3V logic families-verified across the full temperature and voltage range.
What is the power-up behavior of the DS1100LU-20/T&R?
The DS1100LU-20/T&R exhibits a defined power-up time of 200μs, during which outputs remain in a high-impedance or indeterminate state until internal biasing stabilizes. After tPU, all taps begin propagating input transitions with full delay accuracy. This behavior is tested and guaranteed across -40°C to +85°C and 3.0V–3.6V supply conditions.
Is the DS1100LU-20/T&R RoHS-compliant and lead(Pb)-free?
Yes, the DS1100LU-20/T&R is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix in its full ordering code (e.g., DS1100LU-20+/T&R). It supports lead-free reflow soldering up to +260°C peak temperature and meets JEDEC J-STD-020 moisture sensitivity level 1 requirements.
