Analog Devices Inc./Maxim Integrated DS1100Z-45/T&R

Overview

DS1100Z-45/T&R from Maxim Integrated is a 5-tap silicon delay line providing precisely spaced delays of 9ns, 18ns, 27ns, 36ns, and 45ns at each tap, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads per tap - used for digital signal timing alignment in high-speed logic systems.

For engineers reviewing the DS1100Z-45/T&R datasheet, DS1100Z-45/T&R pinout, DS1100Z-45/T&R application, or DS1100Z-45/T&R equivalent, key selection considerations include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, and edge-aligned delay reproducibility for pulse shaping and skew compensation.

Technical Context

The DS1100Z-45/T&R implements an all-silicon delay architecture with five fixed, equally spaced output taps derived from a monolithic CMOS delay chain. It reproduces both leading and trailing edges with matched propagation characteristics, ensuring symmetrical delay behavior independent of input pulse duty cycle.

Each tap delivers deterministic delay values referenced to the same input edge (1.5V threshold), with delay tolerance specified as ±4ns for the 45ns nominal delay over full industrial temperature range (-40°C to +85°C) and ±5% for delays >40ns under voltage variation (4.75V–5.25V).

FAQ

What is the exact delay value at TAP 5 for DS1100Z-45/T&R?

The DS1100Z-45/T&R delivers a nominal delay of 45ns from the IN pin to the TAP 5 output, with a guaranteed tolerance of ±4ns over the full industrial temperature range (-40°C to +85°C) and supply voltage (4.75V–5.25V). This value is factory-trimmed and verified per Table 1 in the official DS1100 datasheet.

Is DS1100Z-45/T&R compatible with 3.3V logic systems?

No - DS1100Z-45/T&R is specified only for 5V operation (4.75V–5.25V). Its input thresholds (VIH = 2.2V min, VIL = 0.8V max) and output drive levels are optimized for TTL/CMOS 5V logic families. Interfacing with 3.3V systems requires level translation to avoid undefined logic states or excessive input current.

Does DS1100Z-45/T&R require external passive components for basic operation?

No external passive components are required for core delay functionality. However, a 0.1μF ceramic decoupling capacitor must be placed between VCC and GND pins as close as possible to the DS1100Z-45/T&R package to ensure stable power delivery and minimize supply-induced delay variation.

Can DS1100Z-45/T&R reproduce both rising and falling edges with equal accuracy?

Yes - DS1100Z-45/T&R is explicitly designed for leading- and trailing-edge accuracy, with matched tPLH and tPHL specifications. Both edges are delayed by the same nominal amount (e.g., 45ns at TAP 5), and delay tolerance applies equally to rising and falling transitions per datasheet Note 1.

What is the maximum load each tap of DS1100Z-45/T&R can drive?

Each tap of DS1100Z-45/T&R can drive up to 10 LS-TTL loads (equivalent to 10 × 74LS inputs), as confirmed in the General Description section. This corresponds to a low-level output current (IOL) of 12mA and high-level output current (IOH) of -1mA under minimum VCC conditions.
