Product details
Overview
DS1100U-300+ from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precise fixed delays of 60ns, 120ns, 180ns, 240ns, and 300ns per tap. It operates at 5V, reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, and drives up to 10 LS-TTL loads per output-used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100U-300+ datasheet, DS1100U-300+ pinout, DS1100U-300+ application, or DS1100U-300+ equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, low-power CMOS operation, 5V supply stability, and µMAX footprint constraints for high-density PCBs.
Technical Context
The DS1100U-300+ implements an all-silicon delay architecture with five equally spaced taps derived from a monolithic CMOS delay chain. Each tap provides deterministic propagation delay referenced to the input edge at 1.5V threshold, with matched rise/fall delay tracking ensuring symmetrical edge reproduction.
Delay values are specified with ±4ns absolute tolerance over –40°C to +85°C for the 300ns version, and delay variation remains unidirectional across temperature and voltage-i.e., all taps speed up or slow down together, preserving inter-tap spacing integrity under varying conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 60ns / 120ns / 180ns / 240ns / 300ns - fixed, factory-trimmed delays enabling precise multi-point timing alignment |
| Delay Tolerance | ±4ns (–40°C to +85°C) - guarantees maximum deviation from nominal tap delay under full industrial temperature range |
| Supply Voltage | 4.75V to 5.25V - supports stable operation across standard 5V rail tolerances without regulation overhead |
| Input Compatibility | TTL/CMOS - accepts 0.8V/2.2V logic thresholds, eliminating level-shifting in mixed-logic systems |
| Output Drive | 12mA sink / –1mA source - sufficient to directly drive 10× 74LS loads without external buffers |
| Power Consumption | 30–50mA active current at 1MHz - enables predictable thermal budgeting in timing-critical subsystems |
| Input Capacitance | 5–10pF - minimizes signal reflection and loading on high-speed source drivers |
Pinout & Package
DS1100U-300+ uses the 8-pin µMAX® package (outline U8+1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V power supply input - must be decoupled locally with 0.1µF ceramic capacitor |
| 2 | TAP 1 | First delayed output - delivers 60ns delay from IN, compatible with 74LS fanout |
| 3 | TAP 3 | Third delayed output - delivers 180ns delay, aligned with center tap for symmetric delay distribution |
| 4 | TAP 5 | Fifth delayed output - delivers 300ns delay, highest delay tap for longest timing interval generation |
| 5 | IN | Digital input - accepts TTL/CMOS logic levels; 3ns max rise/fall time recommended for accuracy |
| 6 | TAP 2 | Second delayed output - delivers 120ns delay, used for intermediate timing points |
| 7 | TAP 4 | Fourth delayed output - delivers 240ns delay, bridges gap between mid- and full-range delays |
| 8 | GND | Ground reference - requires low-impedance connection to minimize ground bounce on multi-tap switching |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid component reliability risks and enables wafer-level testing for consistent delay matching |
| Five equally spaced taps | Enables linear interpolation of timing intervals without external logic or programmable elements |
| Leading- and trailing-edge accuracy | Ensures pulse-width preservation across all taps-critical for duty-cycle-sensitive applications like PWM synchronization |
| Vapor-phase, IR, and wave solderable | Supports standard SMT reflow profiles including Pb-free (260°C peak) without delamination or parametric shift |
| Stable delay over temperature/voltage | Unidirectional delay drift preserves relative tap spacing-enabling robust multi-clock domain alignment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-300+ | Hybrid construction; higher temperature coefficient (±100ppm/°C vs. ±30ppm/°C); larger SO-8 footprint | Limited to commercial temp range (0°C to +70°C); lower reliability in thermal cycling environments | Select only if legacy hybrid design reuse is required and industrial temperature operation is not needed. |
| MAX9600EUA+ | Programmable 8-tap delay; SPI interface; 3.3V-only operation; higher quiescent current (85mA) | Requires microcontroller coordination; supports dynamic delay adjustment but adds firmware complexity | Choose when variable delay tuning is essential and system already includes SPI-controlled timing resources. |
Compared with DS1000Z-300+, DS1100U-300+ offers superior temperature stability and smaller µMAX packaging; versus MAX9600EUA+, it provides simpler, zero-config fixed-delay operation ideal for deterministic real-time systems where programmability adds unnecessary overhead.

FAQ
What is the operating temperature range for DS1100U-300+?
The DS1100U-300+ is rated for continuous operation from –40°C to +85°C. This industrial temperature range is validated per the Absolute Maximum Ratings and DC/AC Electrical Characteristics tables in the official datasheet, with delay tolerances explicitly specified across this full span. DS1100U-300+ maintains its ±4ns tap delay accuracy within this range, making it suitable for deployment in outdoor, automotive, and factory-floor environments where ambient temperatures fluctuate widely.
Does DS1100U-300+ support both rising and falling edge delays?
Yes, DS1100U-300+ reproduces both leading and trailing edges with equal precision-each tap delivers matched tPLH (rising) and tPHL (falling) delays. The datasheet confirms identical delay tolerance specifications for both edge types, and the internal all-silicon architecture ensures symmetrical propagation characteristics. This behavior is critical for preserving pulse width integrity in DS1100U-300+ applications such as PWM signal conditioning and clock deskewing.
Can DS1100U-300+ drive standard TTL loads directly?
Yes, DS1100U-300+ can drive up to 10 LS-TTL loads per tap, as confirmed by its IOL = 12mA and IOH = –1mA specifications at VCC = 4.75V. Its output structure meets TTL voltage thresholds (VOH ≥ 2.4V, VOL ≤ 0.5V) under load, eliminating the need for external buffer stages in most logic interfacing scenarios. This capability is explicitly verified in the DS1100U-300+ test conditions and supported by its "TTL/CMOS-compatible" feature listing.
Is DS1100U-300+ RoHS-compliant and lead-free?
Yes, DS1100U-300+ carries the "+" suffix, which Maxim defines as indicating a lead(Pb)-free and RoHS-compliant package. The datasheet specifies a peak reflow temperature of +260°C for lead-free processes and references compliance in the Ordering Information and Package Information sections. DS1100U-300+ uses matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 standards.
How does DS1100U-300+ differ from the DS1100Z-300+ variant?
DS1100U-300+ uses the 8-pin µMAX package (3mm × 3mm), while DS1100Z-300+ uses the larger 8-pin SO (150-mil) package. Both share identical electrical specifications, delay values, and temperature ratings-but DS1100U-300+ enables higher PCB density and improved thermal performance due to its smaller footprint and exposed thermal pad. The "U" and "Z" suffixes denote package type only; DS1100U-300+ is not a functional derivative or revision of DS1100Z-300+.
