Analog Devices Inc./Maxim Integrated DS1004Z-3/T&R

Overview

DS1004Z-3/T&R from Dallas Semiconductor (now Maxim Integrated) is a 5-tap all-silicon delay line IC providing precise, temperature-stable clock/data delays with nominal input-to-tap1 delay of 5 ns, tap-to-tap delays of 3 ns, and ±0.75 ns nominal tap-to-tap tolerance. It delivers five synchronized delayed outputs in an 8-pin SOIC package and is used in high-speed digital timing alignment, clock deskewing, and signal path synchronization.

For engineers reviewing the DS1004Z-3/T&R datasheet, DS1004Z-3/T&R pinout, DS1004Z-3/T&R application, or DS1004Z-3/T&R equivalent, key selection criteria include input-to-tap1 delay accuracy (±1.5 ns over temp/voltage), leading/trailing edge symmetry preservation, CMOS/TTL compatibility, and 150-mil SOIC packaging for high-density PCB layouts.

Technical Context

The DS1004Z-3/T&R implements a monolithic silicon delay chain with five fixed-output taps, where each tap provides deterministic propagation delay relative to the input. Its architecture ensures matched rise/fall edge delays and maintains input waveform symmetry across all outputs.

It operates at VCC = 5.0 V ±5% over 0°C to +70°C, supports up to 10 LS-TTL loads per output, and meets J-STD-020A soldering standards for vapor phase, IR, and wave reflow. Input pulse width must be ≥40% of Tap 5 tPLH for guaranteed timing accuracy.

Key Specifications

Pinout & Package

DS1004Z-3/T&R is housed in a 150-mil 8-pin SOIC (small outline integrated circuit) package, compliant with JEDEC MS-012, with gull-wing leads and 1.27 mm pitch. The package is vapor-phase, IR, and wave solderable per J-STD-020A.

Manufacturer

Dallas Semiconductor, now part of Analog Devices (via Maxim Integrated acquisition), specializes in precision timing, memory, and mixed-signal ICs for industrial, communications, and computing applications.

The DS1004 product line was designed to replace quartz-based and RC delay modules with highly stable, all-silicon alternatives for high-speed digital synchronization in commercial-temperature environments.

FAQ

What is the nominal input-to-tap1 delay for DS1004Z-3/T&R?

The DS1004Z-3/T&R has a nominal input-to-tap1 delay of 5 ns, with a total tolerance of ±1.5 ns over the full operating temperature range (0°C to +70°C) and supply voltage variation (VCC = 4.75 V to 5.25 V). This value is fixed per the DS1004Z-3 variant and confirmed in Table 2 of the official datasheet. DS1004Z-3/T&R achieves this via calibrated on-die delay elements, not external components.

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

Yes, DS1004Z-3/T&R guarantees matched leading and trailing edge precision: tPLH and tPHL delays are specified identically across all taps, preserving input signal symmetry. Per datasheet Note 3 and Table 1, delay accuracy applies to both edges within the same ±1.5 ns tolerance window, making DS1004Z-3/T&R suitable for clock distribution where duty cycle integrity is critical.

What is the maximum load drive capability per output of DS1004Z-3/T&R?

Each output of DS1004Z-3/T&R can drive up to 10 LS-TTL loads, corresponding to IOL = 12 mA (VOL = 0.5 V) and IOH = –1 mA (VOH = 4 V) under VCC = 4.75 V. This is verified in the DC Electrical Characteristics table. DS1004Z-3/T&R maintains timing accuracy under this load, provided proper 15 pF output capacitance and 50 Ω source impedance are maintained per test conditions.

Is DS1004Z-3/T&R RoHS compliant and lead-free?

DS1004Z-3/T&R was originally manufactured prior to full RoHS enforcement and uses a leaded SOIC package. While Maxim Integrated later introduced RoHS-compliant variants (e.g., DS1004Z-3+), the DS1004Z-3/T&R part number specifically denotes the legacy leaded tape-and-reel version. Customers requiring RoHS compliance should verify current status with Analog Devices' product change notices or select DS1004Z-3+ if available.

Can DS1004Z-3/T&R be used with 3.3 V logic systems?

No, DS1004Z-3/T&R is strictly a 5 V device: its Absolute Maximum Ratings specify VCC = –1.0 V to +7.0 V, but DC Electrical Characteristics are only guaranteed at VCC = 4.75 V to 5.25 V. Operation below 4.75 V risks failure to meet timing specs (e.g., increased delay variation, reduced drive strength). For 3.3 V systems, DS1004Z-3/T&R requires level translation; it is not 3.3 V tolerant.
