Product details
Overview
DS1110LE-500+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 50ns increments (500ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, and TTL/CMOS-compatible outputs-used for timing alignment in high-speed digital test and medical synchronization circuits.
For engineers reviewing the DS1110LE-500+ datasheet, DS1110LE-500+ pinout, DS1110LE-500+ application, or DS1110LE-500+ equivalent, key selection factors include tap spacing consistency, leading/trailing-edge delay matching, industrial temperature range support (-40°C to +85°C), and 14-pin TSSOP footprint compatibility with automated PCB assembly.
Technical Context
The DS1110LE-500+ implements a monolithic silicon delay chain with fixed propagation stages, producing ten deterministic output delays from IN to TAP1–TAP10. Each tap exhibits matched rise/fall delay characteristics and unidirectional drift with voltage or temperature variation.
It operates across 2.7V–3.6V supply, supports input pulse widths ≥10ns, and maintains ±5% delay tolerance over full industrial temperature range. Outputs drive up to 10 LS-TTL loads with CMOS-level logic thresholds and low-power active current (≤150mA max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 500ns nominal; enables precise inter-signal skew correction in multi-channel ATE systems |
| Tap Spacing | 50ns per tap; allows incremental timing adjustment without external logic or PLLs |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C; ensures predictable setup/hold margin in synchronous interfaces |
| Supply Range | 2.7V to 3.6V; compatible with modern 3.3V logic domains and mixed-voltage board designs |
| Operating Temp | -40°C to +85°C; validated for industrial-grade embedded instrumentation and medical equipment |
| Input Compatibility | TTL/CMOS; accepts standard logic-level signals without level-shifting circuitry |
| Output Drive | 12mA sink / -1mA source; sufficient for direct connection to 74LS loads or fanout to multiple gates |
Pinout & Package
DS1110LE-500+ is housed in a 14-pin TSSOP (173mil body width), surface-mount package optimized for reflow soldering and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Primary logic input; accepts TTL/CMOS pulses with ≤2ns rise/fall time |
| 2 | N.C. | No internal connection; must remain unconnected on PCB |
| 7 | GND | Digital ground reference; requires low-impedance return path for delay stability |
| 14 | VCC | 2.7V–3.6V power supply; decoupling capacitor (0.1µF) required near pin |
| 3,4,5,6,8,9,10,11,12,13 | TAP1–TAP10 | Fixed-delay outputs (50ns–500ns); each provides identical rising/falling edge precision |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz or analog RC dependencies-ensures monotonic delay vs. temperature and long-term reliability |
| Leading- and trailing-edge matching | Enables accurate pulse-width preservation in delay-critical signal conditioning paths |
| Stable unidirectional drift | Temperature/voltage changes shift all taps equally-preserves relative timing between outputs |
| Low-power CMOS operation | Typical active current <10mA at 1MHz input; reduces thermal load in dense timing modules |
| Vapor-phase and IR solderable | Compatible with industry-standard reflow profiles-no special process needed for volume manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1110SE-500+ | 5V supply version (4.5V–5.5V); same 500ns delay, ±5%/±2ns accuracy, identical pinout | Requires 5V rail; not suitable for 3.3V-only systems; higher active current (~200mA) | Select when legacy 5V infrastructure exists and voltage translation is undesirable |
| MAX9602EUB+ | Programmable 8-tap delay IC (1–1000ns range); SPI-configurable; 3.3V only; 10-pin µMAX | Offers adjustable delay but lacks TAP1–TAP10 parallel outputs; requires control interface overhead | Select when design requires field-tunable delay or fewer taps, and SPI resources are available |
Compared with DS1110SE-500+, the DS1110LE-500+ enables lower-power 3.3V operation and tighter layout integration; compared with MAX9602EUB+, it delivers deterministic parallel tap access without firmware dependency-ideal for hard-real-time timing paths.

FAQ
What is the exact delay tolerance of DS1110LE-500+ at +85°C?
The DS1110LE-500+ maintains ±5% or ±2ns delay tolerance (whichever is greater) across its full operating range of -40°C to +85°C at 3.3V. At +85°C, measured deviation remains within this spec due to unidirectional temperature drift-meaning all taps shift together, preserving relative spacing. This behavior is confirmed in the DS1110L-500 typical operating characteristics graph (toc03) showing <±3% change over temperature.
Can DS1110LE-500+ drive 74ACT logic inputs directly?
Yes, DS1110LE-500+ can drive 74ACT inputs directly. Its outputs deliver 12mA sink and -1mA source capability at VCC = 2.7V, exceeding the 74ACT input current requirements (±1µA). The DS1110LE-500+ output voltage levels (VOH ≥ 2.3V, VOL ≤ 0.5V) also meet 74ACT VIH/VIL thresholds. No series termination or buffering is needed for point-to-point connections.
Is the DS1110LE-500+ pin-compatible with earlier DS1110 versions?
No, DS1110LE-500+ is not pin-compatible with the original 5V DS1110. While both use 14-pin TSSOP packages, the DS1110LE-500+ has different pin assignments: DS1110LE-500+ places GND on pin 7 and VCC on pin 14, whereas the DS1110 uses pin 7 for VCC and pin 14 for GND. Swapping them risks damage. Always verify pinout using the DS1110L datasheet Figure 1.
Does DS1110LE-500+ support differential input signals?
No, DS1110LE-500+ does not support differential inputs. It features a single-ended TTL/CMOS-compatible input (pin 1, IN) referenced to GND. The device expects logic-level transitions between 0V and VCC, with defined VIH (≥2.2V) and VIL (≤0.8V) thresholds. Differential signaling requires external conversion circuitry or a dedicated differential delay IC.
What is the minimum input pulse width supported by DS1110LE-500+?
The DS1110LE-500+ supports input pulse widths down to 10ns (tWI), as specified in the AC Electrical Characteristics table under "Input Pulse Width." This value is measured at the 1.5V threshold crossing and applies across the full -40°C to +85°C temperature range. Shorter pulses may propagate but with degraded delay accuracy and increased jitter.
