Analog Devices Inc./Maxim Integrated DS1004Z-5

Overview

DS1004Z-5 from Dallas Semiconductor is a 5-tap all-silicon delay line with precise tap-to-tap delays of 5 ns, 10 ns, 15 ns, 20 ns, and 25 ns (input-to-tap), ±1.0 ns nominal tap-to-tap tolerance, ±1.75 ns over temperature/voltage, and CMOS/TTL-compatible outputs capable of driving 10 LS loads. It serves as a high-speed timing control element in digital test equipment and clock distribution networks.

For engineers reviewing the DS1004Z-5 datasheet, DS1004Z-5 pinout, DS1004Z-5 application, or DS1004Z-5 equivalent, key selection criteria include input-to-tap1 delay (5 ns), tap-to-tap accuracy (±1.0 ns nominal), output drive strength (10 LS loads), edge symmetry preservation, and SOIC-8 packaging for space-constrained PCB layouts.

Technical Context

The DS1004Z-5 implements a monolithic silicon delay architecture with five deterministic, fixed-time output taps derived from a single CMOS/TTL-compatible input. All delays are referenced to the 1.5 V switching threshold on both rising and falling edges, ensuring symmetrical propagation.

It operates across 0°C to +70°C and V_CC = 4.75 V to 5.25 V, with input-to-tap1 delay guaranteed ≥5 ns and cumulative delays up to 25 ns at Tap 5. Output rise/fall times are ≤2.5 ns into 15 pF, supporting high-frequency pulse alignment in logic validation systems.

FAQ

What is the guaranteed minimum input-to-Tap1 delay for DS1004Z-5?

The DS1004Z-5 guarantees a minimum input-to-Tap1 delay of 5 ns under all specified operating conditions (0°C to +70°C, V_CC = 4.75 V to 5.25 V). This value is confirmed in Table 2 of the official datasheet and forms the foundation for all subsequent tap delays: Tap2 at ≥10 ns, Tap3 at ≥15 ns, Tap4 at ≥20 ns, and Tap5 at ≥25 ns. The DS1004Z-5 achieves this via monolithic silicon delay elements with matched transistor sizing and layout.

Does DS1004Z-5 support both rising and falling edge delay accuracy?

Yes, the DS1004Z-5 provides matched delay accuracy on both rising and falling edges, measured at the 1.5 V switching threshold. Its design preserves input signal symmetry, with tap-to-tap tolerances of ±1.0 ns nominal and ±1.75 ns over temperature and voltage for both edge polarities. This dual-edge fidelity is explicitly documented in the "Leading and trailing edge precision preserves the input symmetry" feature and verified in AC Electrical Characteristics.

Can DS1004Z-5 drive standard TTL logic directly?

Yes, the DS1004Z-5 is CMOS-designed with TTL compatibility and rated to drive up to 10 LS-TTL loads per output. Its output high current (I_OH) is –1.0 mA at V_OH = 4.0 V, and output low current (I_OL) is 12 mA at V_OL = 0.5 V, meeting LS-TTL interface requirements. This eliminates the need for level-shifting buffers in mixed-logic systems using the DS1004Z-5.

What is the maximum operating temperature range for DS1004Z-5?

The DS1004Z-5 is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade range is defined in the Absolute Maximum Ratings and DC/AC Electrical Characteristics sections. Storage temperature extends to –55°C to +125°C, but functional operation outside 0°C to +70°C is not guaranteed. Thermal derating or validation beyond this range requires consultation of the DS1004Z-5 datasheet's environmental test data.

Is DS1004Z-5 pin-compatible with other DS1004 variants like DS1004Z-2 or DS1004Z-3?

Yes, all DS1004Z-x variants (including DS1004Z-2, DS1004Z-3, DS1004Z-4, and DS1004Z-5) share identical 8-pin SOIC pinouts, electrical interfaces, and supply requirements. Only the nominal tap-to-tap delays differ: DS1004Z-5 provides 5 ns spacing, while DS1004Z-2 offers 2 ns spacing. This allows direct PCB replacement when delay requirements change, provided timing margins accommodate the new delay profile.
