Analog Devices Inc./Maxim Integrated DS1100Z-50+T&R

Overview

DS1100Z-50+T&R from Maxim Integrated is a 5-tap silicon delay line providing precisely spaced 10ns, 20ns, 30ns, 40ns, and 50ns delays at 5V supply, designed for edge-aligned timing control in digital logic systems, with TTL/CMOS compatibility and industrial temperature operation (-40°C to +85°C).

For engineers reviewing the DS1100Z-50+T&R datasheet, DS1100Z-50+T&R pinout, DS1100Z-50+T&R application, or DS1100Z-50+T&R equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range), output drive capability (10 × 74LS loads per tap), SO-8 package footprint, and lead-free RoHS compliance.

Technical Context

The DS1100Z-50+T&R implements an all-silicon delay architecture with five fixed, equally spaced taps-no external components or trimming required. Each tap reproduces both leading and trailing edges with matched precision, enabling synchronous multi-phase signal alignment in clock distribution, pulse shaping, and setup/hold time adjustment circuits.

It operates exclusively at 5V (4.75V–5.25V), draws ≤50mA active current, and maintains delay stability across -40°C to +85°C. Input-to-tap delay tolerance is ±4ns for all taps under full industrial temperature and voltage conditions, with no variation between rising/falling edge delays.

Key Specifications

Pinout & Package

DS1100Z-50+T&R is housed in an 8-pin SOIC package (150 mils wide, outline S8+4), compatible with standard surface-mount assembly processes including vapor-phase, IR, and wave soldering.

FAQ

What is the nominal delay progression across taps for DS1100Z-50+T&R?

The DS1100Z-50+T&R provides five equally spaced delays: TAP 1 = 10ns, TAP 2 = 20ns, TAP 3 = 30ns, TAP 4 = 40ns, and TAP 5 = 50ns. This 10ns step interval is factory-trimmed and guaranteed across the full -40°C to +85°C operating range. Each tap reproduces both rising and falling edges with matched delay, making DS1100Z-50+T&R suitable for pulse-width-critical applications.

Is DS1100Z-50+T&R pin-compatible with earlier DS1000-series delay lines?

Yes, DS1100Z-50+T&R uses the same 8-pin SOIC (150-mil) package and identical pinout as DS1000Z-50+T&R, enabling drop-in replacement. However, DS1100Z-50+T&R improves delay stability (±4ns vs >±10ns), adds RoHS compliance, and eliminates hybrid component wear-out mechanisms. The DS1100Z-50+T&R retains full electrical compatibility with legacy DS1000 designs.

What is the maximum capacitive load each tap of DS1100Z-50+T&R can drive?

Each tap of DS1100Z-50+T&R is rated to drive up to 10 standard 74LS logic inputs, equivalent to ~200pF total load capacitance. Driving heavier loads may degrade delay accuracy and edge fidelity. For loads exceeding this specification, a buffer such as 74AC04 should be used. The DS1100Z-50+T&R datasheet specifies output current limits of -1mA (IOH) and +12mA (IOL) under worst-case conditions.

Does DS1100Z-50+T&R require external power supply decoupling?

Yes, DS1100Z-50+T&R requires a local 0.1μF ceramic capacitor between VCC (Pin 1) and GND (Pin 8), placed within 5mm of the package. This decoupling is essential to suppress supply noise that could modulate delay values. The DS1100Z-50+T&R exhibits sensitivity to VCC ripple due to its all-silicon delay structure; inadequate decoupling may cause delay variation beyond the specified ±4ns tolerance.

Can DS1100Z-50+T&R operate at voltages other than 5V?

No, DS1100Z-50+T&R is specified only for 5.0V ±5% operation (4.75V–5.25V). Its delay values, drive strength, and timing margins are characterized exclusively at this supply range. Operation outside this window violates Absolute Maximum Ratings and voids timing guarantees. The DS1100Z-50+T&R is not compatible with 3.3V or mixed-voltage systems without level translation.
