Product details

Overview

DS1007S-3 from Dallas Semiconductor (now Maxim Integrated) is a 7-channel all-silicon delay line in 16-pin SOIC, providing four 3 ns fixed delays on outputs OUT1–OUT4 and three 10 ns fixed delays on OUT5–OUT7, with ±2 ns tolerance at 25°C, used for timing alignment in high-speed digital logic interfaces.

For engineers reviewing the DS1007S-3 datasheet, DS1007S-3 pinout, DS1007S-3 application, or DS1007S-3 equivalent, this device supports precise edge-aligned signal deskewing in TTL/CMOS systems requiring sub-nanosecond jitter control, multi-output synchronization, and board-level timing calibration without external passive networks.

Technical Context

The DS1007S-3 implements seven independent, factory-programmed CMOS delay paths with no internal feedback or reconfigurability - each output reproduces its input logic state after a fixed propagation delay. All delays are specified for rising-edge t_PLH only, with unidirectional temperature/voltage tracking across outputs of the same group.

It operates strictly at V_CC = 5.0 V ±5%, draws up to 70 mA active current, and requires no external components or configuration. Input pulse width must be ≥100% of t_PLH, and output loading is defined as one 74F04 gate equivalent.

Key Specifications

Parameter	Value and Actual Design Meaning
Delay Outputs	7 independent buffered outputs: OUT1–OUT4 = 3 ns, OUT5–OUT7 = 10 ns
Delay Accuracy	±2 ns tolerance at 25°C, rising-edge only (t_PLH)
Supply Voltage	4.75 V to 5.25 V - operation outside this range invalidates timing specs
Input Compatibility	TTL/CMOS logic levels: VIH ≥ 2.2 V, VIL ≤ 0.8 V
Output Drive	I_OL = 12 mA min at VOL = 0.5 V; IOH = –1 mA max at VOH = 2.4 V
Operating Temp	0°C to +70°C - delay drift not characterized outside this range
Power Consumption	40–70 mA active current - scales with output loading and frequency

Pinout & Package

DS1007S-3 is housed in a 16-pin SOIC (300-mil width), surface-mount package with standard JEDEC MS-012AC footprint and vapor-phase/wave-solder compatible construction.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN7	Independent logic inputs	Each drives one dedicated delay path; no shared input bus or enable
OUT1–OUT7	Buffered delayed outputs	Fixed delay per pin: OUT1–OUT4 = 3 ns, OUT5–OUT7 = 10 ns
VCC	Positive supply	Must be decoupled locally; noise on VCC directly impacts delay stability
GND	Ground reference	Common return for all inputs, outputs, and supply - critical for delay repeatability

Key Features

Feature	Design Value
All-silicon architecture	Eliminates hybrid/ceramic delay lines - improves long-term reliability and thermal stability
Factory-set fixed delays	No external tuning required; eliminates potentiometers, RC networks, or layout-dependent trace delays
Grouped delay accuracy	OUT1–OUT4 track together; OUT5–OUT7 track together - enables correlated timing adjustments
Low-power CMOS design	Enables integration into power-constrained logic subsystems without thermal derating
TTL/CMOS-compatible I/O	Direct interface with 74F, 74LS, and modern 5V logic families without level-shifting

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	Delays: 3/4/5/6/9/13/18 ns - non-uniform spacing across outputs	Suitable for asymmetric deskew where individual channel offsets differ	Select DS1007S-1 when channel-specific fine-grained delay variation is required
DS1007S-4	Delays: 4/4/4/4/12/12/12 ns - uniform 4 ns on first four, 12 ns on last three	Better margin for 5V logic with slower rise times due to longer base delay	Choose DS1007S-4 if system timing budget allows +1 ns margin on short-path delays

Compared with DS1007S-1 and DS1007S-4, the DS1007S-3 offers the tightest uniformity within each output group (3 ns ×4, 10 ns ×3), making it optimal for applications requiring identical delay replication across subsets of channels - such as quad-data lane alignment or triple-clock domain isolation.

FAQ

What is the exact delay value for each output on the DS1007S-3?

The DS1007S-3 has four outputs with 3 ns delay (OUT1–OUT4) and three outputs with 10 ns delay (OUT5–OUT7), all measured as t_PLH at 25°C with V_CC = 5.0 V. These values are factory-programmed and not adjustable. The DS1007S-3 datasheet Table 1 confirms this configuration as the defining characteristic of the -3 variant.

Does the DS1007S-3 support both rising- and falling-edge delays?

No - the DS1007S-3 specifies delay only for rising-edge propagation (t_PLH). Falling-edge delay (t_PHL) is not characterized in the official datasheet, and design must assume asymmetry. The DS1007S-3 is intended for applications where rising-edge alignment is the primary timing constraint.

Can the DS1007S-3 operate at 3.3 V?

No - the DS1007S-3 is rated exclusively for V_CC = 4.75 V to 5.25 V. Operation at 3.3 V falls outside absolute maximum ratings and will result in undefined delay behavior, reduced noise margin, and potential functional failure. The DS1007S-3 requires a dedicated 5 V rail.

Is the DS1007S-3 pin-compatible with other DS1007 variants like DS1007S-1 or DS1007S-4?

Yes - all DS1007S-x variants share identical 16-pin SOIC pinout, power, ground, and I/O assignments. The only difference is factory-programmed delay values per output. No PCB change is needed when substituting between DS1007S-1, DS1007S-3, or DS1007S-4, provided system timing margins accommodate the new delay profile.

What is the maximum operating frequency supported by the DS1007S-3?

The DS1007S-3 does not specify a maximum frequency - instead, it requires input pulse width ≥100% of the shortest delay (i.e., ≥3 ns). With t_WI ≥ 3 ns and period ≥ 1 µs per test conditions, the practical upper limit is ~1 MHz for guaranteed spec-compliant operation; higher rates may function but fall outside characterized performance.
