Analog Devices Inc./Maxim Integrated DS1100Z-150+T

Overview

DS1100Z-150+T from Maxim Integrated is a 5-tap silicon delay line IC providing precisely spaced 30ns, 60ns, 90ns, 120ns, and 150ns delays at each tap, operating from 4.75V to 5.25V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads per tap in high-speed digital timing alignment applications.

For engineers reviewing the DS1100Z-150+T datasheet, DS1100Z-150+T pinout, DS1100Z-150+T application, or DS1100Z-150+T equivalent, key selection considerations include tap delay accuracy across temperature, leading/trailing edge matching, TTL/CMOS compatibility, SO-8 package footprint, and industrial-grade reliability for signal synchronization in test equipment and logic interface circuits.

Technical Context

The DS1100Z-150+T implements an all-silicon delay line architecture with five fixed, equally spaced delay taps derived from a monolithic CMOS timing circuit - no external components or trimming required. It reproduces both rising and falling edges with matched propagation delay, enabling precise pulse-width preservation across all outputs.

Each tap delivers deterministic delay values referenced to the input signal's 1.5V crossing point, with delay tolerances specified as ±4ns (≤40ns delays) or ±13% (>40ns delays) over full industrial temperature range and supply voltage variation. Input-to-output timing is fully characterized under 50Ω source impedance and 74F04-equivalent loading.

FAQ

What is the nominal delay value for each tap of the DS1100Z-150+T?

The DS1100Z-150+T provides five equally spaced delays: TAP 1 = 30ns, TAP 2 = 60ns, TAP 3 = 90ns, TAP 4 = 120ns, and TAP 5 = 150ns - all referenced to the 1.5V input crossing point and guaranteed over -40°C to +85°C. These values are fixed and factory-trimmed; no external adjustment is possible. The DS1100Z-150+T achieves this using monolithic CMOS delay elements, ensuring consistent tap-to-tap spacing without drift.

Does the DS1100Z-150+T support both rising and falling edge delays with equal accuracy?

Yes, the DS1100Z-150+T is explicitly designed to reproduce both leading and trailing edges with equal precision - tPLH and tPHL are matched within ±4ns for delays ≤40ns and ±13% for longer delays. This edge symmetry ensures pulse-width integrity across all five taps, making the DS1100Z-150+T suitable for applications like clock/data deskewing where duty cycle preservation is essential.

What is the maximum capacitive load the DS1100Z-150+T can drive per tap?

The DS1100Z-150+T is rated to drive up to 10 LS-TTL loads per tap, equivalent to ~10 × 20pF input capacitance and 400µA DC load current. Its output stage delivers 12mA sink and -1mA source capability under VCC = 4.75V. Exceeding this load may degrade delay accuracy and edge rate; for heavier loads, buffer stages are recommended. The DS1100Z-150+T's drive strength is verified under 74F04-equivalent test conditions.

Is the DS1100Z-150+T RoHS-compliant and compatible with lead-free reflow processes?

Yes, the "+T" suffix in DS1100Z-150+T indicates a lead(Pb)-free, RoHS-compliant SO-8 package qualified for lead-free reflow up to +260°C peak temperature. The device supports vapor-phase, IR, and wave soldering per Maxim's package specifications. The DS1100Z-150+T's die attach, wire bond, and mold compound meet JEDEC J-STD-020D moisture sensitivity level 1 requirements.

Can the DS1100Z-150+T operate outside the 5V supply range?

No - the DS1100Z-150+T is specified only for VCC = 4.75V to 5.25V. Absolute maximum rating allows -0.5V to +6.0V on any pin, but functional operation outside the 5V range is not characterized or guaranteed. Supply voltage directly affects delay values (±13% tolerance applies over 4.75V–5.25V), and operation below 4.75V risks output logic level violation and increased ICC. The DS1100Z-150+T must be powered from a regulated 5V rail.
