Product details
Overview
DS1044R-10+ from Maxim Integrated (formerly Dallas Semiconductor) is a 4-channel, all-silicon, high-speed delay line with nominal 10 ns per-output delay, ±1.5 ns initial tolerance, and ±1.0 ns additional variation over 0°C–70°C and 4.75 V–5.25 V supply. It provides independent buffered outputs capable of driving 10 LS-TTL loads and preserves input signal symmetry on both leading and trailing edges - used in digital timing alignment, clock skew correction, and pulse-width stabilization circuits.
For engineers reviewing the DS1044R-10+ datasheet, DS1044R-10+ pinout, DS1044R-10+ application, or DS1044R-10+ equivalent, key selection factors include guaranteed 10 ns delay accuracy, 14-pin SOIC (150 mil) package compatibility, TTL/CMOS input compatibility, output drive strength, and temperature/voltage stability across industrial operating conditions.
Technical Context
The DS1044R-10+ implements four independent logic-buffered delay paths within a single monolithic silicon die, each with matched tPLH and tPHL propagation characteristics. Its architecture ensures edge-aligned delay for both rising and falling transitions, with no internal PLL or feedback - pure fixed-delay analog/digital hybrid timing.
It operates exclusively at +5 V (4.75–5.25 V), draws 45 mA typical active current, and delivers 2.0–2.5 ns output rise/fall times into 15 pF load. Input thresholds comply with TTL/CMOS levels (VIH ≥ 2.2 V, VIL ≤ 0.8 V), and output drive meets LS-TTL sink/source requirements (IOL = 12 mA, IOH = –1.0 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delay | 10 ns per output - fixed, factory-trimmed delay with no external adjustment required |
| Initial Tolerance | ±1.5 ns at +25°C, VCC = 5.0 V - sets baseline timing uncertainty before environmental variation |
| Tolerance Over Temp/VCC | ±1.0 ns across 0°C–70°C and 4.75–5.25 V - enables stable delay in unregulated industrial power environments |
| Output Drive | 12 mA sink / –1.0 mA source - sufficient to directly drive 10 LS-TTL inputs without buffering |
| Rise/Fall Time | 2.0–2.5 ns into 15 pF - supports clean edge integrity up to ~200 MHz signal bandwidth |
| Supply Voltage | 4.75–5.25 V - compatible with standard +5 V logic rails and tolerant of common power rail ripple |
| Operating Temp | 0°C to 70°C - rated for commercial/industrial ambient environments, not extended temp |
Pinout & Package
DS1044R-10+ is housed in a 14-pin SOIC package (150 mil width), pin-compatible with the DIP variant but surface-mount optimized. All NC pins are internally unconnected and must remain floating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 14 | NC | No internal connection - must be left unconnected; no pull-up/down or routing required |
| 2, 4, 5, 6 | OUT1–OUT4 | Buffered delay outputs - each delivers identical 10 ns delayed copy of corresponding input |
| 7, 10, 11, 12 | IN1–IN4 | Independent TTL/CMOS-compatible inputs - accept standard logic-level signals with 10 pF input capacitance |
| 9 | VCC | +5 V power supply - requires local 0.1 µF ceramic decoupling adjacent to pin |
| 13 | GND | Ground reference - shared return for all four channels; low-impedance layout critical for delay stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates quartz or RC-based drift; guarantees long-term aging stability and shock resistance |
| Leading & trailing edge precision | Maintains input duty cycle integrity - essential for symmetric clock distribution and pulse shaping |
| Four independent buffered delays | Enables parallel timing alignment of multiple signals without crosstalk or loading interaction |
| Vapor phase, IR, and wave solder compatible | Supports full industrial reflow and through-hole assembly processes without reliability degradation |
| 10 LS-TTL load drive per output | Reduces need for external fanout buffers in dense logic systems, lowering BOM count and board area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1044-10+ | 14-pin DIP package; identical electrical specs and delay value | Through-hole assembly only; unsuitable for high-density SMT layouts | Select DS1044-10+ only when legacy DIP footprint or manual prototyping is required |
| MAX9622ESE+ | Single 10 ns delay channel; 16-pin SOIC; higher supply range (2.7–5.5 V); lower drive (8 mA) | Limited to one delay path; lacks multi-channel integration; supports mixed-voltage systems | Choose MAX9622ESE+ when system uses <3.3 V logic or only one delay channel is needed |
Compared with DS1044-10+ and MAX9622ESE+, the DS1044R-10+ uniquely combines quad-channel 10 ns delay, industrial-grade SOIC packaging, and LS-TTL drive strength - making it optimal for space-constrained, multi-signal timing alignment where pin count and board area are critical.

FAQ
What is the guaranteed delay accuracy of DS1044R-10+ over temperature and voltage?
The DS1044R-10+ guarantees ±1.0 ns additional delay variation across the full operating range of 0°C to 70°C and 4.75 V to 5.25 V supply voltage, on top of its ±1.5 ns initial tolerance at +25°C. This means total delay deviation remains within ±2.5 ns under worst-case environmental and supply conditions - verified per Dallas Semiconductor datasheet revision 021798.
Can DS1044R-10+ drive standard TTL loads directly?
Yes, DS1044R-10+ can directly drive up to 10 LS-TTL loads per output, with IOL = 12 mA and IOH = –1.0 mA specified at VCC = 4.75 V. Its output structure meets LS-TTL voltage and current thresholds, eliminating the need for external buffer stages in most legacy logic interfacing scenarios involving the DS1044R-10+.
Is DS1044R-10+ pin-compatible with DS1044-10+?
Yes, DS1044R-10+ is pin-compatible with DS1044-10+, sharing identical 14-pin SOIC (DS1044R) and 14-pin DIP (DS1044) footprints and pin functions. Both use the same IN1–IN4, OUT1–OUT4, VCC, GND, and NC assignments - enabling direct substitution when migrating from through-hole to surface-mount assembly for the DS1044R-10+.
Does DS1044R-10+ require external components for stable operation?
No external timing components are required for DS1044R-10+ operation. However, a 0.1 µF ceramic decoupling capacitor must be placed between VCC (pin 9) and GND (pin 13) as close as possible to the device. This is mandatory to suppress supply noise that could modulate delay accuracy - a requirement explicitly stated in the DS1044R-10+ datasheet for stable 10 ns performance.
What is the maximum input frequency supported by DS1044R-10+?
The DS1044R-10+ does not specify a maximum input frequency, but its 2.0–2.5 ns output rise/fall times and 100 ns minimum input pulse width (per tWI specification) imply reliable operation up to approximately 5–10 MHz for repetitive waveforms. For single-shot or low-duty-cycle pulses, the DS1044R-10+ accepts inputs with >100 ns width and maintains full 10 ns delay accuracy - confirmed in the AC Electrical Characteristics table.
