Product details

Overview

DS1007S-1 from Dallas Semiconductor (now Maxim Integrated) is a 7-channel all-silicon delay line in 16-pin SOIC, delivering fixed, factory-set delays of 3 ns, 4 ns, 5 ns, 6 ns, 9 ns, 13 ns, and 18 ns (t_PLH, rising edge), with ±2 ns tolerance at 25°C, V_CC = 5.0 V, used for timing alignment in high-speed digital logic interfaces.

For engineers reviewing the DS1007S-1 datasheet, DS1007S-1 pinout, DS1007S-1 application, or DS1007S-1 equivalent, this device supports precise edge-aligned signal skew correction in TTL/CMOS systems, requires no external components, operates within 0°C to 70°C, and is compatible with vapor-phase, IR, and wave soldering processes.

Technical Context

The DS1007S-1 implements seven independent, unidirectional CMOS delay paths with fixed propagation delays referenced to the input rising edge only; each output reproduces the input logic state after its assigned t_PLH delay. All delays are trimmed during manufacturing and stable across voltage (4.75–5.25 V) and temperature (0–70°C).

No internal feedback, PLL, or re-timing circuitry is present - it is a passive, open-loop delay element. Delay variation between outputs tracks unidirectionally with temperature/voltage changes, enabling predictable relative skew management in multi-channel synchronization.

Key Specifications

Parameter	Value and Actual Design Meaning
Delay Outputs	7 independent outputs (OUT1–OUT7) with fixed t_PLH: 3/4/5/6/9/13/18 ns
Delay Accuracy	±2 ns at 25°C, V_CC = 5.0 V - ensures sub-nanosecond jitter margin in clock/data alignment
Supply Voltage	4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS rails without regulation
Input Compatibility	TTL/CMOS logic levels (V_IL ≤ 0.8 V, V_IH ≥ 2.2 V) - interoperable with 74F/74AS/74HC families
Output Drive	I_OL = 12 mA min., I_OH = –1 mA - sufficient to drive one 74F04 input per output
Operating Temp	0°C to 70°C - rated for commercial-grade embedded and instrumentation applications
Power Consumption	I_CC = 40–70 mA typical - low static current enables use in power-constrained logic subsystems

Pinout & Package

DS1007S-1 is housed in a 16-pin SOIC (300-mil width), surface-mount package compliant with JEDEC MS-012AC. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN7	Independent logic inputs	Each drives one dedicated delay path; no crosstalk or shared input buffering
OUT1–OUT7	Dedicated delayed logic outputs	Each delivers its factory-set t_PLH delay on rising edge only; outputs are buffered and non-inverting
V_CC (Pin 5)	Positive supply	Single 5 V rail powers all seven channels; no separate analog/digital supplies required
GND (Pin 12)	Ground reference	Common return for all inputs, outputs, and internal circuitry; decoupling recommended at pin

Key Features

Feature	Design Value
All-silicon construction	Eliminates hybrid/ceramic delay lines - improves long-term reliability and thermal stability vs. legacy solutions
Factory-trimmed delays	Delays set at wafer test; no field calibration or external tuning components needed
Low-profile SOIC packaging	Enables automated SMT assembly and fits space-constrained PCB layouts (300-mil width)
Rising-edge-only delay accuracy	Guaranteed ±2 ns on t_PLH; trailing-edge delay not specified - suitable for setup/hold timing, not pulse-width preservation
Multi-standard logic compatibility	Accepts TTL and CMOS input thresholds and drives 74F-level loads - simplifies integration across logic families

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-2	Delays: 4/6/8/10/12/14/16 ns - uniformly spaced, higher base delays than DS1007S-1	Suitable for longer-skew correction (e.g., >10 ns inter-channel mismatch); less optimal for fine-grained 3–6 ns alignment	Select DS1007S-2 when system skew exceeds 6 ns and uniform step size is preferred over minimal base delay.
MC100EP195DTG	8-channel ECL differential delay line; 0.1–3.0 ns steps via external resistor; ±0.3 ps jitter	Requires ECL supply (-3.3 V), differential signaling, and external tuning - incompatible with single-ended 5 V logic	Choose MC100EP195DTG only for ultra-low-jitter, programmable, high-frequency (>1 GHz) differential systems where DS1007S-1's fixed 5 V CMOS architecture is insufficient.

Compared with DS1007S-2 and MC100EP195DTG, the DS1007S-1 offers the lowest base delay (3 ns), best cost/performance ratio for 5 V single-ended logic, and zero configuration overhead - making it optimal for commercial-grade skew correction where fixed, factory-verified delays suffice.

FAQ

What is the guaranteed delay accuracy of the DS1007S-1 across temperature and voltage?

The DS1007S-1 guarantees ±2 ns delay tolerance at 25°C and V_CC = 5.0 V. Over full operating conditions (0°C to 70°C, V_CC = 4.75–5.25 V), delay variation remains monotonic and bounded - all outputs track unidirectionally, preserving relative skew. Absolute worst-case deviation is not specified beyond room-temperature test condition, so system-level margining must account for temperature-induced drift.

Does the DS1007S-1 support both rising- and falling-edge delay accuracy?

No. The DS1007S-1 specifies delay accuracy only for the rising edge (t_PLH). Trailing-edge (t_PHL) delay is not characterized or guaranteed. The device is intended for applications where rising-edge timing alignment is critical - such as clock/data setup windows - and not for pulse-width preservation or dual-edge-sensitive circuits.

Can the DS1007S-1 be used with 3.3 V logic systems?

No. The DS1007S-1 is strictly a 5 V device: V_CC must be 4.75–5.25 V, and input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.2 V) assume 5 V logic levels. Driving it from 3.3 V sources risks marginal VIH compliance; connecting its 5 V outputs to 3.3 V inputs risks overvoltage damage unless level-shifting is implemented externally.

How many outputs does the DS1007S-1 drive simultaneously, and what load is supported?

The DS1007S-1 drives all seven outputs concurrently. Each output is specified to drive one 74F04 input load (≈ 20 pF capacitive + 1.6 mA DC), with I_OL ≥ 12 mA and I_OH ≤ –1 mA. Heavier loads increase propagation delay and may degrade edge rate; for >1 74F load per output, buffer fanout ICs are recommended.

Is the DS1007S-1 pin-compatible with other DS1007 variants like DS1007S-2 or DS1007S-3?

Yes. All DS1007S-x variants share identical 16-pin SOIC pinout, power, ground, and I/O assignments. Only the factory-programmed delay values differ per part number. No PCB redesign is needed when substituting between DS1007S-1, DS1007S-2, etc., provided system timing margins accommodate the new delay profile.
