Product details
Overview
DS1007S-2/T&R from Dallas Semiconductor (now Maxim Integrated) is a 7-channel all-silicon delay line in 16-pin SOIC package, delivering fixed, factory-set delays of 4 ns, 6 ns, 8 ns, 10 ns, 12 ns, 14 ns, and 16 ns (tPLH, rising edge), with ±2 ns tolerance at 25°C. It operates at 5 V, supports TTL/CMOS logic levels, and is used for timing alignment in high-speed digital systems such as clock skew correction and pulse width adjustment.
For engineers reviewing the DS1007S-2/T&R datasheet, DS1007S-2/T&R pinout, DS1007S-2/T&R application, or DS1007S-2/T&R equivalent, key selection criteria include channel count, delay precision across temperature (0°C to 70°C), SOIC-16 surface-mount compatibility, low-power CMOS operation, and factory-programmed delay values per output.
Technical Context
The DS1007S-2/T&R implements seven independent, non-reconfigurable silicon-based delay paths - four outputs (OUT1–OUT4) optimized for 3–10 ns range, three (OUT5–OUT7) for 9–40 ns range. All delays are specified at the 1.5 V threshold on rising edges only, with unidirectional drift across voltage/temperature variations within a given speed grade.
It requires no external components, draws ≤70 mA active current at 5 V, and features TTL/CMOS-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.2 V), 5–10 pF input capacitance, and 12 mA low-level output drive capability - enabling direct interfacing with 74F-series logic loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay Values (tPLH) | 4 ns, 6 ns, 8 ns, 10 ns, 12 ns, 14 ns, 16 ns - factory-set, rising-edge-only, ±2 ns accuracy at 25°C |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5 V logic rails; no regulation required |
| Operating Temp | 0°C to 70°C - suitable for commercial-grade embedded and instrumentation applications |
| Input Logic Levels | VIL ≤ 0.8 V, VIH ≥ 2.2 V - ensures robust interfacing with TTL and CMOS sources |
| Output Drive | IOL = 12 mA - sufficient to drive one 74F04 input gate per output without buffering |
| Power Consumption | ICC = 40–70 mA - low static power enables use in space-constrained, thermally sensitive layouts |
| Input Capacitance | CIN = 5–10 pF - minimizes signal reflection and loading on high-speed source drivers |
Pinout & Package
DS1007S-2/T&R is housed in a 16-pin SOIC (300-mil width) package with gull-wing leads, compatible with vapor phase, IR, and wave soldering processes. Pin 1 is marked by a notch or dot; device is auto-insertable and low-profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN7 | Logic Inputs | Seven independent TTL/CMOS-compatible inputs; each drives one dedicated delay path |
| OUT1–OUT7 | Delayed Outputs | Seven buffered outputs reproducing input logic state after fixed tPLH; no inversion or logic function |
| VCC | Power Supply | +5 V supply pin; must be decoupled locally (typical 0.1 µF ceramic) |
| GND | Ground Reference | Common return for all inputs, outputs, and internal circuitry; critical for delay stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging; improves long-term reliability and thermal stability vs. older LC or SAW delay lines |
| ±2 ns delay tolerance | Enables precise inter-channel timing alignment in multi-clock domain synchronization |
| Factory-programmed delays | Removes need for external RC networks or programmable logic; reduces BOM count and layout complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1007S-1/T&R | Delays: 3 ns, 4 ns, 5 ns, 6 ns, 9 ns, 13 ns, 18 ns - tighter low-end spacing but larger gaps above 10 ns | Better suited for fine-grained skew correction below 10 ns; less optimal for uniform mid-range alignment | Select DS1007S-1/T&R when sub-5 ns resolution is required across first four outputs |
| DS1007S-3/T&R | Delays: 3 ns ×4, 10 ns ×3 - uniform low-delay group + single-step higher delay | Ideal for applications requiring identical short delays on primary signals and consistent longer delay on control/status lines | Choose DS1007S-3/T&R for replicated timing on parallel buses with grouped functional domains |
Compared with DS1007S-1/T&R and DS1007S-3/T&R, DS1007S-2/T&R offers the most balanced progression across its full 7-output set - making it optimal for general-purpose multi-signal alignment where linearly increasing delay steps improve timing margin predictability.

FAQ
What is the operating temperature range for DS1007S-2/T&R?
The DS1007S-2/T&R is rated for operation from 0°C to 70°C. This commercial temperature range is validated across all electrical specifications including delay accuracy (±2 ns), input thresholds, and output drive strength. Operation outside this range may cause uncharacterized drift in tPLH and increased ICC, and is not supported by Dallas Semiconductor's datasheet.
Does DS1007S-2/T&R support both rising- and falling-edge delay measurement?
No - DS1007S-2/T&R delay specifications (tPLH) apply to rising-edge transitions only, measured at the 1.5 V threshold. The datasheet explicitly states trailing-edge accuracy is not guaranteed for OUT1–OUT4, and only OUT5–OUT7 support both edges. For bidirectional delay matching, DS1007S-2/T&R must be used with rising-edge-triggered logic.
Can DS1007S-2/T&R be reprogrammed or adjusted after manufacturing?
No - DS1007S-2/T&R is a factory-programmed, mask-defined silicon delay line with fixed, non-volatile delay values. There are no pins, registers, or external controls for runtime adjustment. Delay values are permanently set during fabrication and cannot be modified in-system or via configuration.
What is the maximum output load capacity for DS1007S-2/T&R?
Each output of DS1007S-2/T&R is characterized to drive one 74F04 input gate under standard test conditions (VOL = 0.5 V, IOL = 12 mA). Driving heavier capacitive or resistive loads may degrade delay accuracy and increase propagation skew; additional buffering is recommended for fan-out >1 or trace lengths >2 inches.
Is DS1007S-2/T&R pin-compatible with other DS1007 variants like DS1007S-1/T&R?
Yes - all DS1007S-x/T&R variants share identical 16-pin SOIC-300 package dimensions, pin numbering, and pin functions (IN1–IN7, OUT1–OUT7, VCC, GND). Delay values differ per variant, but PCB layout, decoupling, and interconnect requirements remain unchanged across the DS1007S family.
