Analog Devices Inc./Maxim Integrated DS1100Z-35/T&R

Overview

DS1100Z-35/T&R from Maxim Integrated is a 5-tap silicon delay line providing fixed, equally spaced delays of 7ns, 14ns, 21ns, 28ns, and 35ns at 5V operation, designed for precise edge-aligned timing in digital signal conditioning circuits, with TTL/CMOS-compatible I/O and industrial temperature range support (-40°C to +85°C).

For engineers reviewing the DS1100Z-35/T&R datasheet, DS1100Z-35/T&R pinout, DS1100Z-35/T&R application, or DS1100Z-35/T&R equivalent, key selection criteria include tap delay precision (±4ns over full temperature range), 5V supply compatibility, SO-8 package footprint, output drive capability (10 × 74LS loads), and leading/trailing-edge fidelity.

Technical Context

The DS1100Z-35/T&R implements an all-silicon delay architecture with five fixed-output taps derived from a monolithic CMOS delay chain, ensuring matched propagation across all taps and unidirectional delay drift under voltage or temperature variation. Each tap reproduces both rising and falling edges with equal accuracy, referenced to the 1.5V logic threshold.

It operates exclusively at 5V (4.75V–5.25V), draws ≤50mA active current, and supports standard reflow soldering profiles including lead-free (260°C). Input pulse width must exceed 20% of Tap 5 delay (≥7ns) for guaranteed timing compliance.

Key Specifications

Pinout & Package

DS1100Z-35/T&R is housed in an 8-pin SOIC package (150 mils wide, outline S8+4), optimized for automated assembly and PCB area efficiency. Pin assignments are standardized across the DS1100Z family.

FAQ

What is the nominal delay value for each tap of the DS1100Z-35/T&R?

The DS1100Z-35/T&R provides five equally spaced nominal delays: Tap 1 = 7ns, Tap 2 = 14ns, Tap 3 = 21ns, Tap 4 = 28ns, and Tap 5 = 35ns. These values are specified at +25°C and 5V, with tolerances of ±4ns over the full industrial temperature range (-40°C to +85°C). All delays are measured at the 1.5V logic threshold for both rising and falling edges.

Is the DS1100Z-35/T&R pin-compatible with other DS1100Z variants?

Yes, the DS1100Z-35/T&R shares identical pinout, package (8-pin SO), and electrical interface with all DS1100Z-xxx variants-including DS1100Z-30/T&R and DS1100Z-40/T&R. The only functional difference is the nominal delay per tap; no PCB layout change is required when substituting within the DS1100Z family.

Does the DS1100Z-35/T&R support lead-free soldering processes?

Yes, the DS1100Z-35/T&R is RoHS-compliant and qualified for lead-free reflow soldering with a peak temperature of +260°C. Its SO-8 package (S8+4 outline) meets JEDEC J-STD-020D moisture sensitivity level 1 requirements and supports vapor-phase, infrared, and wave soldering.

Can the DS1100Z-35/T&R drive standard TTL loads directly?

Yes, each tap of the DS1100Z-35/T&R can drive up to 10 × 74LS loads (12mA sink / -1mA source), meeting standard TTL fan-out requirements without external buffers. This capability is verified across the full operating temperature and voltage range (4.75V–5.25V, -40°C to +85°C).

How does the DS1100Z-35/T&R ensure matching between leading and trailing edge delays?

The DS1100Z-35/T&R uses a monolithic CMOS delay chain architecture that inherently tracks tPLH and tPHL across temperature and voltage. Both delays are specified at the same 1.5V threshold and exhibit identical tolerance (±4ns), ensuring pulse-width preservation critical for clock/data alignment and glitch-free operation.
