Product details
Overview
DS1010S-250/T&R from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with nominal total delay of 250 ns, ±5% or ±2 ns tolerance, TTL/CMOS-compatible input/output, and 5 V supply. It delivers equally spaced taps (25 ns per tap), leading/trailing edge accuracy, and drives up to 10 × 74LS loads - used in digital timing alignment, pulse shaping, and clock deskew in test instrumentation and industrial control systems.
For engineers reviewing the DS1010S-250/T&R datasheet, DS1010S-250/T&R pinout, DS1010S-250/T&R application, or DS1010S-250/T&R equivalent, key selection factors include tap spacing stability across temperature, edge fidelity for high-speed logic synchronization, SOIC-16 footprint compatibility, and drive strength for legacy TTL fanout requirements.
Technical Context
The DS1010S-250/T&R implements a monolithic CMOS delay chain with 10 fixed-output taps, each delayed by exactly 25 ns from the prior tap (TAP 1 = 25 ns, TAP 10 = 250 ns). Delay accuracy is specified as ±5% or ±2 ns (whichever greater) at 25°C, with additional temperature-induced shift of ±2 ns or ±3% over 0°C–70°C for TAP 10 ≥100 ns.
It operates at 5.0 V ±5%, supports 40 ns minimum input pulse width, and maintains equal precision on both rising (tPLH) and falling (tPHL) edges. Output loading is defined per 74LS gate (≈20 pF), and input capacitance is 5–10 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Operating temp | 0°C to +70°C - suitable for commercial-grade embedded controllers and test equipment |
| Input capacitance | 5–10 pF - minimizes signal reflection and timing skew in high-speed PCB routing |

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 |
|---|---|---|---|
| DS1010-250 | DIP-14 package; same electrical specs, larger footprint, through-hole mounting | Preferred for prototyping, manual assembly, or legacy DIP-based systems | Select DS1010-250 when board real estate is unconstrained and hand-soldering or socket use is required. |
| MAX9602ESE+ | 8-tap, 100–800 ns range, ±1.5% accuracy, SOIC-16, 3.3 V only | Higher accuracy and lower voltage; not drop-in due to VCC and tap count mismatch | Choose MAX9602ESE+ only when 3.3 V operation and tighter tolerance (<±2 ns) are mandatory and tap reduction is acceptable. |
Compared with DS1010-250, the DS1010S-250/T&R offers identical timing performance in a space-saving SOIC-16 package; versus MAX9602ESE+, it provides broader voltage compatibility and full 10-tap functionality but trades off absolute accuracy for cost and legacy interface support.

FAQ
What is the total delay and tap spacing for DS1010S-250/T&R?
The DS1010S-250/T&R provides a total delay of 250 ns at TAP 10, with precisely 25 ns spacing between consecutive taps (TAP 1 = 25 ns, TAP 2 = 50 ns, ..., TAP 10 = 250 ns). This fixed, linear progression is guaranteed across operating temperature (0°C to +70°C) within ±5% or ±2 ns tolerance, whichever is greater - confirmed in Table 1 and AC Electrical Characteristics of the DS1010 datasheet.
Is DS1010S-250/T&R pin-compatible with the DIP version DS1010-250?
No, DS1010S-250/T&R is not pin-compatible with DS1010-250. The DS1010S-250/T&R uses a 16-pin SOIC package with specific pin assignments (e.g., IN on Pin 1, VCC on Pin 12), while DS1010-250 uses a 14-pin DIP with different pinout (e.g., IN on Pin 1, VCC on Pin 14). Layout redesign is required when migrating between packages - refer to mechanical drawings in DS1010 datasheet Sections 1 and 2.
What load can each tap of DS1010S-250/T&R drive?
Each tap of DS1010S-250/T&R is rated to drive up to 10 × 74LS-type loads, corresponding to 12 mA sink current (IOL) and –1 mA source current (IOH) under VCC = 4.75 V. This is verified in DC Electrical Characteristics (Page 3) and ensures reliable interfacing with legacy TTL logic without external buffers - provided PCB trace capacitance remains below 20 pF per node.
Does DS1010S-250/T&R support both rising and falling edge delays?
Yes, DS1010S-250/T&R guarantees matched delay accuracy for both signal edges: tPLH (rising edge) and tPHL (falling edge) are identical within ±2 ns or ±5% tolerance (whichever greater), as stated in Features and AC Electrical Characteristics. This symmetry preserves pulse width integrity - essential for applications like strobe generation and clock deskew where duty cycle fidelity matters.
What is the recommended power supply decoupling for DS1010S-250/T&R?
A 0.1 µF ceramic capacitor placed as close as possible to the VCC (Pin 12) and GND (Pin 13) pins is required for stable operation of DS1010S-250/T&R. This mitigates switching noise from internal delay chain activity and prevents supply-induced delay variation - consistent with DC Electrical Characteristics test conditions and Maxim's application guidance for silicon delay lines.
