Product details
Overview
DS1010S-75 from Dallas Semiconductor (now Maxim Integrated) is a 10-tap all-silicon delay line with nominal total delay of 75 ns, ±5% or ±2 ns tolerance, TTL/CMOS-compatible input/output, and 5 V supply. It delivers precise leading and trailing edge delays across ten equally spaced taps and drives up to 10 × 74LS loads per tap. Used in digital timing alignment, clock skew correction, and pulse width adjustment in test instrumentation and industrial control systems.
For engineers reviewing the DS1010S-75 datasheet, DS1010S-75 pinout, DS1010S-75 application, or DS1010S-75 equivalent, key selection criteria include tap-to-tap uniformity, edge accuracy under temperature variation, SOIC-16 footprint compatibility, and load-driving capability for legacy logic families.
Technical Context
The DS1010S-75 implements a monolithic CMOS delay chain architecture with fixed, equally spaced taps-TAP 1 through TAP 10-each delivering incremental delay of 7.5 ns. Delay accuracy is specified at ±5% or ±2 ns (whichever greater) over 0°C to 70°C, with unidirectional drift across all taps under voltage or temperature change.
It operates at 5.0 V ±5%, supports 40 ns minimum input pulse width, and guarantees tPLH/tPHL matching between rising and falling edges. Output drive strength meets 74LS fanout requirements (IOL = 12 mA, IOH = –1.0 mA), and input thresholds comply with TTL logic levels (VIH ≥ 2.2 V, VIL ≤ 0.8 V).
Key Specifications

Pinout & Package
DS1010S-75 is packaged in a 16-pin SOIC (300-mil width), optimized for surface-mount assembly and reduced PCB area versus DIP variants.
| Pin/Terminal | Circuit Role | Design Meaning |

FAQ
What is the total delay and tap spacing for DS1010S-75?
The DS1010S-75 provides a total delay of 75 ns from input (IN) to TAP 10 output, with equally spaced taps delivering 7.5 ns increments. This fixed delay structure is factory-trimmed and specified at ±5% or ±2 ns (whichever greater) over 0°C to 70°C. Each tap's delay is referenced to the same input edge, ensuring consistent relative timing across all outputs in the DS1010S-75.
Is DS1010S-75 pin-compatible with the DIP version DS1010-75?
No, DS1010S-75 is not pin-compatible with DS1010-75. The DS1010S-75 uses a 16-pin SOIC package with a different pin assignment-including dedicated NC pins and rearranged tap ordering-while DS1010-75 uses a 14-pin DIP. Board layout and footprint must be redesigned when migrating between these packages, though electrical behavior and delay values are identical in the DS1010S-75 and DS1010-75.
What logic families can DS1010S-75 directly drive?
The DS1010S-75 can directly drive up to 10 × 74LS-type loads per tap, with IOL = 12 mA and IOH = –1.0 mA at VCC = 4.75 V. Its TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and CMOS-compatible operation allow seamless integration with 74HC, 74HCT, and earlier bipolar logic families without level-shifting. This drive capability is confirmed across the full operating temperature range for the DS1010S-75.
Does DS1010S-75 support both rising and falling edge delays with equal accuracy?
Yes, DS1010S-75 guarantees matched leading-edge (tPLH) and trailing-edge (tPHL) delay accuracy-both specified at ±5% or ±2 ns (whichever greater). This symmetry is achieved via internal circuit balancing and validated across temperature and voltage. The DS1010S-75 reproduces input waveform edges with equal fidelity, making it suitable for applications requiring precise pulse width preservation or dual-edge timing alignment.
What is the maximum operating temperature range for DS1010S-75?
The DS1010S-75 is rated for commercial operation from 0°C to 70°C. Its delay accuracy degrades predictably within this range: for delays <100 ns (like the DS1010S-75's 75 ns), temperature-induced shift is ±1 ns or ±9% (whichever greater) from 25°C to either 0°C or 70°C. This specification is fully characterized and documented in the DS1010S-75 datasheet's AC Electrical Characteristics table.
