Product details
Overview
DS1010S-400 from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with fixed 400 ns total delay (40 ns/tap), TTL/CMOS-compatible input, 5 V supply, and 16-pin SOIC package. It delivers precise leading/trailing edge delay accuracy of ±5% or ±2 ns (whichever greater) and drives up to 10 × 74LS loads per tap - used in digital timing alignment, pulse shaping, and clock deskew circuits.
For engineers reviewing the DS1010S-400 datasheet, DS1010S-400 pinout, DS1010S-400 application, or DS1010S-400 equivalent, key selection factors include tap-to-tap uniformity, temperature-stable delay shift (±2 ns or ±3% for ≥100 ns variants), SOIC footprint compatibility, and 5 V DC electrical compliance per JEDEC Level A.
Technical Context
The DS1010S-400 implements a monolithic CMOS tapped delay chain with 10 equally spaced outputs, where TAP 10 provides the full 400 ns nominal delay. All taps reproduce both rising and falling edges with matched tPLH/tPHL propagation characteristics under 5 V ±5% supply.
Delay stability is maintained across 0°C to 70°C operating range, with temperature-induced shift bounded at ±2 ns or ±3% (whichever greater) due to unidirectional variation across taps - critical for synchronous signal alignment in logic interface and test equipment.

| 10 | TAP 9 | Ninth output tap delivering 360 ns delay; used for near-final-stage timing adjustment | |
| 11 | TAP 5 | Fifth output tap delivering 200 ns delay; common reference point for dual-path synchronization | |
| 12 | VCC | +5 V power supply pin; requires local 0.1 µF ceramic decoupling adjacent to pin | |
| 13 | 16 | GND | Ground reference for all I/O and internal circuitry; connects to system ground plane |
| 14 | NC | No internal connection; no electrical function; may be used as thermal relief or keep-out marker | |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1010-400 | 14-pin DIP package; same 400 ns delay, identical electrical specs, but through-hole mounting | Preferred for prototyping, legacy systems, or mixed-technology boards requiring DIP sockets | Select DS1010-400 when board assembly includes wave soldering of through-hole components or socket-based validation fixtures. |
| MAX5517EUA+ | 8-tap, 12-bit programmable delay IC; SPI-configurable; 1.6–12.8 ns step resolution; 5 V supply | Used where dynamic delay adjustment is required; lacks fixed-tap fanout capability of DS1010S-400 | Choose MAX5517EUA+ only if application demands runtime reconfiguration - otherwise DS1010S-400 offers lower cost and simpler integration. |
Compared with DS1010-400 and MAX5517EUA+, the DS1010S-400 provides optimal balance of fixed-tap simplicity, SOIC manufacturability, and guaranteed 40 ns tap resolution - making it ideal for production systems where delay stability and layout efficiency outweigh programmability needs.

FAQ
What is the total delay and tap spacing of the DS1010S-400?
The DS1010S-400 provides a total delay of 400 ns at TAP 10, with precisely equal 40 ns spacing between consecutive taps (TAP 1 = 40 ns, TAP 2 = 80 ns, ..., TAP 10 = 400 ns). This fixed, linear progression is guaranteed across temperature and supply voltage within datasheet limits and enables predictable multi-point timing in digital systems.
Is the DS1010S-400 pin-compatible with the through-hole DS1010-400 variant?
No - the DS1010S-400 uses a 16-pin SOIC package while the DS1010-400 uses a 14-pin DIP. Pin counts, layouts, and terminal assignments differ significantly; they are functionally equivalent but not mechanically or electrically pin-compatible. Board redesign is required when substituting one for the other.
Does the DS1010S-400 support both rising and falling edge delay accuracy?
Yes - the DS1010S-400 is explicitly characterized for both tPLH (rising edge) and tPHL (falling edge) delays, with identical ±5% or ±2 ns accuracy specification applied to each. This ensures consistent pulse width preservation across all 10 taps, critical for applications like strobe generation and clock deskew.
What is the maximum capacitive load the DS1010S-400 can drive per tap?
The DS1010S-400 is rated to drive up to 10 × 74LS-type loads per tap, corresponding to approximately 10 × 20 pF (200 pF total) at 5 V. Exceeding this load may degrade delay accuracy and edge fidelity; external buffers are recommended for heavier fanout or longer traces.
Can the DS1010S-400 operate outside the 0°C to 70°C range?
No - the DS1010S-400 is specified only for commercial temperature operation (0°C to 70°C). While storage rating extends to –55°C to +125°C, functional performance outside the operating range is not guaranteed. For extended temperature applications, consult Maxim Integrated's automotive-qualified alternatives or derating guidance.
