Product details
Overview
DS1005M-100 from Dallas Semiconductor is a 5-tap all-silicon delay line with fixed tap delays of 20 ns, 40 ns, 60 ns, 80 ns, and 100 ns; ±2 ns or ±3% delay tolerance; TTL/CMOS-compatible input; capable of driving ten 74LS loads per tap; used in digital timing alignment, clock skew correction, and pulse shaping circuits.
For engineers reviewing the DS1005M-100 datasheet, DS1005M-100 pinout, DS1005M-100 application, or DS1005M-100 equivalent, key selection factors include tap delay accuracy over temperature (0°C to 70°C), leading/trailing edge matching, 8-pin DIP package compatibility, and 5.0 V ±5% supply operation.
Technical Context
The DS1005M-100 implements a monolithic silicon delay structure with five equally spaced, buffered output taps. Each tap reproduces the input logic level after its specified fixed delay, with identical tPLH and tPHL values per tap and unidirectional delay drift across temperature/voltage.
It operates at 5.0 V ±5%, draws 40–70 mA active current, and maintains ±2 ns or ±3% delay accuracy on both rising and falling edges under 0°C to 70°C ambient conditions, with input pulse width ≥40% of Tap 5 tPLH.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Tap Delays | 20 ns / 40 ns / 60 ns / 80 ns / 100 ns - fixed, equally spaced delays referenced to input 1.5 V crossing point |
| Delay Tolerance | ±2 ns or ±3%, whichever greater - guarantees worst-case timing margin for setup/hold validation |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS logic rails without regulation |
| Output Drive | 12 mA sink / –1 mA source - sufficient for direct interface to 74LS loads (10 per tap) |
| Operating Temp | 0°C to 70°C - commercial-grade range suitable for industrial control and instrumentation |
| Input Capacitance | 5–10 pF - low loading enables clean edge integrity with minimal signal distortion |
Pinout & Package
DS1005M-100 is packaged in an 8-pin DIP (300-mil) with gull-wing leads, auto-insertable and wave-solder compatible. Pin 1 = IN, Pin 2 = TAP 2, Pin 3 = TAP 4, Pin 4 = GND, Pin 5 = VCC, Pin 6 = TAP 1, Pin 7 = TAP 3, Pin 8 = TAP 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended TTL/CMOS-compatible input; accepts 0–3.0 V low, 3.0–5.0 V high pulses |
| 2 | TAP 2 | Buffered output delayed by 40 ns; drives up to ten 74LS loads |
| 3 | TAP 4 | Buffered output delayed by 80 ns; matches TAP 2 drive strength and edge fidelity |
| 4 | GND | Digital ground reference; must be connected to system ground plane for stable delay performance |
| 5 | VCC | +5 V power supply; requires local 0.1 µF ceramic decoupling adjacent to pin |
| 6 | TAP 1 | Buffered output delayed by 20 ns; first in sequence, used for coarse timing alignment |
| 7 | TAP 3 | Buffered output delayed by 60 ns; center tap, critical for symmetric pulse interpolation |
| 8 | TAP 5 | Buffered output delayed by 100 ns; maximum delay tap, defines total pipeline latency |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid component aging and thermal mismatch; ensures long-term delay stability |
| Leading & trailing edge accuracy | tPLH and tPHL match within tolerance - enables precise pulse width preservation across all taps |
| 5-tap equal spacing | Fixed 20 ns step between consecutive taps - simplifies multi-phase clock generation and delay interpolation |
| Low-power CMOS design | 40–70 mA active current at 5 V - reduces thermal load in dense PCB layouts |
| TTL/CMOS input compatibility | VIH ≥ 2.2 V, VIL ≤ 0.8 V - interoperable with legacy 5 V logic families without level shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5-tap fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1005-100 (14-pin DIP) | Same delay values and electrical specs; differs only in 14-pin DIP package with NC pins and different pinout | Requires PCB redesign due to 14-pin footprint and relocated TAP outputs | Select when legacy board layout uses 14-pin DIP sockets or hybrid lead configurations |
| DS1005S-100 (16-pin SOIC) | Identical delay and AC specs; packaged in 16-pin SOIC with NC pins occupying unused positions | Suitable for surface-mount production but requires rework of land pattern and stencil | Select for space-constrained designs needing automated assembly and higher density |
Compared with DS1005-100 and DS1005S-100, the DS1005M-100 offers identical timing performance in a compact 8-pin DIP footprint-reducing board area by 43% versus the 14-pin version while retaining through-hole assembly compatibility and eliminating NC pins that complicate routing.

FAQ
What is the exact delay value for each tap on the DS1005M-100?
The DS1005M-100 provides five fixed, equally spaced delays: TAP 1 = 20 ns, TAP 2 = 40 ns, TAP 3 = 60 ns, TAP 4 = 80 ns, and TAP 5 = 100 ns. These values are measured at the 1.5 V crossing point for both rising (tPLH) and falling (tPHL) edges, with accuracy guaranteed to ±2 ns or ±3%, whichever is greater, over 0°C to 70°C and 4.75 V to 5.25 V supply.
Is the DS1005M-100 pin-compatible with other DS1005 variants?
No, the DS1005M-100 is not pin-compatible with DS1005-100 (14-pin DIP) or DS1005S-100 (16-pin SOIC). Its 8-pin DIP pinout places TAP outputs on pins 2, 3, 6, 7, and 8 with dedicated IN, VCC, and GND-requiring unique PCB layout. The DS1005M-100 eliminates NC pins present in other variants, optimizing routing efficiency.
Can the DS1005M-100 drive standard TTL loads directly?
Yes, the DS1005M-100 can drive up to ten 74LS loads per tap, meeting standard TTL fan-out requirements. Its output sink current is 12 mA (min) and source current is –1 mA (min) at VCC = 4.75 V, ensuring robust logic-level transitions without external buffering in most 5 V digital systems.
Does the DS1005M-100 support operation outside the 0°C to 70°C range?
No, the DS1005M-100 is specified only for 0°C to 70°C operation per its datasheet. While storage temperature extends to –55°C to +125°C, functional performance-including delay accuracy and output drive-is not guaranteed outside the commercial temperature range. Extended-range versions require custom ordering through Maxim/Dallas.
How does the DS1005M-100 handle input pulse width and duty cycle variations?
The DS1005M-100 specifies minimum input pulse width as 40% of Tap 5 tPLH (i.e., ≥40 ns for DS1005M-100), and permits wider pulses or non-50% duty cycles. However, delay accuracy remains valid only when input rise/fall times are ≤3.0 ns and source impedance ≤50 Ω; deviations may degrade edge fidelity and increase jitter.
