Analog Devices Inc./Maxim Integrated DS1004Z-3+T

Overview

DS1004Z-3+T from Maxim Integrated (formerly Dallas Semiconductor) is a 5-tap all-silicon delay line IC providing precise, temperature-stable tap-to-tap delays of 3 ns with ±0.75 ns nominal tolerance and ±1.5 ns input-to-tap 1 delay tolerance over 0°C to +70°C. It delivers five delayed CMOS/TTL-compatible clock phases from a single input, with leading/trailing edge symmetry preservation, and drives up to 10 LS loads. Used in high-speed timing alignment for test equipment and digital signal synchronization.

For engineers reviewing the DS1004Z-3+T datasheet, DS1004Z-3+T pinout, DS1004Z-3+T application, or DS1004Z-3+T equivalent, key selection criteria include tap delay accuracy, edge symmetry performance, output drive strength, SOIC-8 thermal and soldering compatibility, and input-to-output delay stability across voltage and temperature.

Technical Context

The DS1004Z-3+T implements a monolithic silicon delay chain architecture with five fixed-delay taps derived from a single input signal. Each tap provides deterministic propagation delay with matched rising/falling edge timing-critical for maintaining signal duty cycle integrity in high-speed logic systems.

It operates at VCC = 5.0 V ±5% and guarantees input-to-tap1 delay of 5 ns (min), with subsequent taps spaced at precisely 3 ns intervals (tap1–tap2 = 3 ns, tap2–tap3 = 3 ns, etc.), resulting in cumulative delays of 5 ns, 8 ns, 11 ns, 14 ns, and 17 ns. Delay tolerances are specified separately for nominal conditions and over full operating range.

Key Specifications

FAQ

What is the exact input-to-tap1 delay specification for DS1004Z-3+T?

The DS1004Z-3+T guarantees a minimum input-to-tap1 delay of 5 ns under all operating conditions (0°C to +70°C, VCC = 4.75–5.25 V). Its nominal input-to-tap1 delay is 5 ns, with a total tolerance of ±1.5 ns over temperature and voltage, as confirmed in Table 1 of the official datasheet. This value is fixed and does not vary with frequency or load within rated specifications. The DS1004Z-3+T maintains this delay stability without external calibration.

Does DS1004Z-3+T support both rising and falling edge delays with equal accuracy?

Yes, the DS1004Z-3+T preserves leading and trailing edge precision equally-its delay accuracy applies identically to both tPLH (rising edge) and tPHL (falling edge) measurements, as explicitly stated in the "DESCRIPTION" section and verified in Table 1 notes. This symmetry ensures duty cycle integrity across all five taps, which is essential for applications like clock deskewing and high-speed sampling where edge alignment affects timing margins. The DS1004Z-3+T achieves this via matched internal path design.

What is the maximum capacitive load the DS1004Z-3+T outputs can drive reliably?

The DS1004Z-3+T is characterized to drive up to 10 LS-TTL loads (equivalent to ~15 pF total load capacitance), as specified in the "DESCRIPTION" and confirmed in the "TEST CONDITIONS" section. Output rise/fall times remain within 2.0–2.5 ns under this load. Exceeding 15 pF may degrade edge fidelity and increase delay uncertainty. For heavier loads, external buffer stages are recommended. The DS1004Z-3+T's drive strength is fixed and does not require external termination resistors.

Is DS1004Z-3+T RoHS compliant and lead-free?

Yes, DS1004Z-3+T is RoHS-compliant and lead-free, consistent with Maxim Integrated's transition to green packaging standards. The "+T" suffix denotes tape-and-reel packaging with lead-free terminations and compliance with JEDEC J-STD-020A for moisture sensitivity and reflow profiles. No exemptions apply, and the device meets EU RoHS Directive 2011/65/EU requirements. DS1004Z-3+T documentation confirms Pb-free plating and halogen-free molding compound.

Can DS1004Z-3+T be used with non-5V logic families?

No-DS1004Z-3+T is designed exclusively for 5 V operation (VCC = 4.75–5.25 V) and CMOS/TTL-compatible signaling levels. Its VIH (2.2 V min) and VIL (0.8 V max) thresholds, along with output drive specs, are optimized for 5 V logic families. It is not compatible with 3.3 V, 2.5 V, or 1.8 V systems without level translation. Using DS1004Z-3+T outside its specified supply range risks parametric failure or reliability degradation. Always operate DS1004Z-3+T within its published DC electrical characteristics.
