Analog Devices Inc./Maxim Integrated DS1100Z-40

Overview

DS1100Z-40 from Maxim Integrated is a 5-tap silicon delay line IC delivering precise, fixed delays of 8ns (TAP1), 16ns (TAP2), 24ns (TAP3), 32ns (TAP4), and 40ns (TAP5) with ±4ns tolerance over -40°C to +85°C, 5V operation, TTL/CMOS-compatible outputs, and ability to drive up to 10 × 74LS loads - used in digital timing alignment, pulse shaping, and clock deskew in industrial control and test equipment.

For engineers reviewing the DS1100Z-40 datasheet, DS1100Z-40 pinout, DS1100Z-40 application, or DS1100Z-40 equivalent, key selection criteria include tap delay accuracy across temperature, leading/trailing edge matching, SO-8 package compatibility, 5V supply stability, and load-driving capability for legacy logic interfacing.

Technical Context

The DS1100Z-40 implements an all-silicon delay architecture with five equally spaced, fixed-delay taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay, enabling symmetrical pulse stretching or phase alignment without duty-cycle distortion.

It operates strictly at 5V (4.75V–5.25V), draws 30–50mA active current, and maintains delay tolerance within ±4ns (for ≤40ns delays) across its full industrial temperature range. Input-to-output timing is measured at the 1.5V threshold, and output loading follows standardized 74F04-equivalent gate conditions.

FAQ

What is the nominal delay value for each tap of the DS1100Z-40?

The DS1100Z-40 provides five fixed delays: TAP1 = 8ns, TAP2 = 16ns, TAP3 = 24ns, TAP4 = 32ns, and TAP5 = 40ns. These values are specified at +25°C and 5V, with monotonic spacing confirmed across temperature and voltage variations. All delays are measured at the 1.5V logic threshold, and the DS1100Z-40 datasheet Table 1 explicitly defines these values for the "-40" variant.

Does the DS1100Z-40 support both rising and falling edge delays with equal accuracy?

Yes, the DS1100Z-40 is designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) are matched within ±4ns over the full -40°C to +85°C range. This symmetry ensures pulse width integrity - critical for applications like strobe generation and clock deskew where duty cycle preservation matters. The DS1100Z-40 datasheet explicitly states this capability in the General Description and AC Electrical Characteristics sections.

What is the maximum capacitive load the DS1100Z-40 outputs can drive?

The DS1100Z-40 outputs are rated to drive up to 10 × 74LS logic inputs, equivalent to ~100pF total load capacitance under standard test conditions. Output drive strength is specified as 12mA sink and -1mA source at VOH = 4V and VOL = 0.5V. Exceeding this load may degrade delay accuracy and edge rate; for heavier loads, external buffer stages are recommended. This specification is confirmed in the DC Electrical Characteristics table of the DS1100Z-40 datasheet.

Is the DS1100Z-40 RoHS-compliant?

Yes, the DS1100Z-40 is RoHS-compliant when ordered with the "+" suffix (e.g., DS1100Z-40+). The ordering information section confirms that "+" denotes lead(Pb)-free/RoHS-compliant packaging. Standard DS1100Z-40 devices without the "+" may contain lead; always verify the full orderable part number and consult Maxim's package documentation for RoHS status. The DS1100Z-40 package outline S8+4 supports both variants.

Can the DS1100Z-40 operate outside the 5V supply range?

No - the DS1100Z-40 is specified only for 5.0V ±5% operation (4.75V to 5.25V). Absolute maximum ratings limit pin voltage to -0.5V to +6.0V, but functional operation outside the 4.75V–5.25V range is not guaranteed. Supply voltages below 4.75V risk increased delay variation and reduced output drive; above 5.25V may accelerate parametric shift or reduce reliability. The DS1100Z-40 DC Electrical Characteristics table conditions all parameters at VCC = 5.0V ±5%.
