Product details
Overview
DS1007S-7 from Maxim Integrated (formerly Dallas Semiconductor) is a 7-channel all-silicon delay line in 16-pin SOIC, delivering fixed delays of 7 ns on outputs OUT1–OUT4 and 25 ns on OUT5–OUT7 with ±2 ns tolerance at 25°C. It operates from 4.75 V to 5.25 V, supports TTL/CMOS logic levels, and is used for precise signal alignment in high-speed digital timing circuits.
For engineers reviewing the DS1007S-7 datasheet, DS1007S-7 pinout, DS1007S-7 application, or DS1007S-7 equivalent, this page provides verified delay values, SOIC package details, input/output terminal roles, real-world use cases in clock deskew and pulse shaping, and two validated alternative part numbers with documented timing and packaging differences.
Technical Context
The DS1007S-7 implements seven independent, factory-programmed CMOS delay paths with unidirectional temperature/voltage tracking across outputs - meaning delay shifts coherently across all channels under varying conditions. Each output reproduces the input logic state after its fixed delay, with leading-edge accuracy only for OUT1–OUT4 and both leading/trailing-edge accuracy for OUT5–OUT7.
It features low-power CMOS operation (typical ICC = 55 mA), 5 V single-supply compatibility, and robust soldering support including vapor phase, IR, and wave processes. Input rise/fall times are specified ≤3 ns, and minimum input pulse width equals the longest programmed delay (25 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay Outputs | OUT1–OUT4: 7 ns; OUT5–OUT7: 25 ns - fixed, factory-set timing offsets for synchronous signal alignment |
| Delay Accuracy | ±2 ns at 25°C - enables sub-nanosecond jitter budget allocation in timing-critical systems |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS logic rails without regulation overhead |
| Input Compatibility | TTL/CMOS - accepts 0.8 V VIL and 2.2 V VIH thresholds, ensuring interoperability with legacy and modern logic families |
| Operating Temp | 0°C to +70°C - rated for commercial-grade industrial control and test equipment environments |
| Package | 16-pin SOIC (300-mil width) - surface-mount footprint with standardized PCB land pattern per drawing 56-G4009-001B |
| Power Dissipation | Typical ICC = 55 mA at 5 V - translates to ~275 mW total active power, suitable for dense board layouts |
Pinout & Package
DS1007S-7 is housed in a 16-pin small-outline integrated circuit (SOIC) package, 300 mil wide, with JEDEC MS-012AC compliant dimensions and thermal profile suitable for vapor phase, IR, and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN7 | Independent logic inputs | Each drives one dedicated delay path; no internal fan-in or logic gating - signals propagate independently |
| OUT1–OUT7 | Dedicated delayed outputs | Output logic state matches input after programmed delay; OUT1–OUT4 lead-edge only; OUT5–OUT7 lead/trail-edge accurate |
| VCC | Positive supply | Single 5 V rail powers all seven delay paths; decoupling capacitor required at pin per layout guidelines |
| GND | Ground reference | Common return for all inputs, outputs, and internal circuitry; must be low-impedance plane connection |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic substrates - improves long-term reliability and reduces cost vs. older delay technologies |
| Seven independent delays | Enables parallel timing adjustment across multiple signal paths without cross-talk or shared resource contention |
| ±2 ns delay tolerance | Supports tight setup/hold margin control in high-speed interfaces such as memory controllers and FPGA I/O banks |
| Auto-insertable SOIC | Compatible with standard SMT pick-and-place equipment and reflow profiles - no manual assembly required |
| TTL/CMOS-compatible I/O | Interoperates directly with 74F, 74ACT, and modern microcontroller GPIO without level-shifting circuitry |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1007-7 | DIP-16 package; identical delay values (7/25 ns) and electrical specs; same 0°C to +70°C rating | Through-hole mounting only; incompatible with SMT production lines; requires socket or wave soldering | Select DS1007-7 only for prototyping, repair, or legacy through-hole designs where SOIC is not feasible |
| MAX9992ETE+ | 8-channel, 1.2 V to 5.5 V supply; programmable delays via SPI (10 ps steps); ±50 ps accuracy; 16-pin TQFN | Requires digital configuration and external clock; supports dynamic delay adjustment; higher precision but greater system complexity | Choose MAX9992ETE+ when adaptive timing control or sub-ns resolution is required - not a drop-in replacement for DS1007S-7 |
Compared with DS1007-7 and MAX9992ETE+, the DS1007S-7 offers fixed, factory-set delays in an SMT-ready SOIC package - ideal for cost-sensitive, high-volume applications where timing stability and simplicity outweigh programmability needs.

FAQ
What is the exact delay configuration of the DS1007S-7?
The DS1007S-7 provides four 7 ns delays on outputs OUT1 through OUT4 and three 25 ns delays on OUT5 through OUT7, with ±2 ns tolerance at 25°C. These values are factory-programmed and cannot be adjusted in-circuit. The DS1007S-7 does not support user-defined delay settings - it is a fixed-function device optimized for repeatable, production-ready timing alignment.
Is the DS1007S-7 RoHS-compliant?
No, the DS1007S-7/T&R variant is not RoHS/lead-free compliant, as confirmed by Maxim's official product listing and materials analysis. It uses leaded solder finish and Pb-containing die attach. For RoHS-compliant alternatives, consider DS1007S-2+ or DS1007S-14+, which carry the '+' suffix and are manufactured with lead-free terminations per JEDEC J-STD-609.
Can the DS1007S-7 operate at 3.3 V?
No, the DS1007S-7 is specified only for 4.75 V to 5.25 V operation. Its DC electrical characteristics - including VIH (2.2 V min), VIL (0.8 V max), and ICC - are characterized exclusively at 5 V ±5%. Operation below 4.75 V may result in undefined output behavior, increased propagation delay variation, or failure to meet the ±2 ns accuracy specification.
Does the DS1007S-7 require external decoupling capacitors?
Yes, the DS1007S-7 requires a 0.1 µF ceramic decoupling capacitor placed as close as possible to the VCC pin (Pin 5) and GND (Pin 12). This is explicitly recommended in the DS1007 datasheet to suppress switching noise and maintain delay stability across all seven channels during simultaneous output transitions.
How does temperature affect DS1007S-7 delay performance?
Delay variation across temperature is unidirectional: all outputs slow down or speed up together as temperature changes. Over the full 0°C to +70°C range, total delay shift remains within ±5% of nominal value (e.g., ±1.25 ns for 25 ns outputs), preserving relative alignment between channels - a key advantage for skew correction applications using the DS1007S-7.
