Analog Devices Inc./Maxim Integrated DS1100Z-30/T&R

Overview

DS1100Z-30/T&R from Maxim Integrated is a 5-tap silicon delay line IC with nominal tap delays of 6ns, 12ns, 18ns, 24ns, and 30ns, operating at 5V with ±4ns delay tolerance over -40°C to +85°C. It reproduces both leading and trailing edges with equal precision, drives up to 10 × 74LS loads per tap, and is housed in an 8-pin SO (150 mils) surface-mount package. It serves as a stable, all-silicon replacement for hybrid delay lines in digital timing alignment circuits.

For engineers reviewing the DS1100Z-30/T&R datasheet, DS1100Z-30/T&R pinout, DS1100Z-30/T&R application, or DS1100Z-30/T&R equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, output drive capability, solderability (vapor-phase/IR/wave), and industrial-grade operating range.

Technical Context

The DS1100Z-30/T&R implements a fixed, passive silicon delay structure - not programmable or voltage-controlled - where each tap provides a deterministic, monotonic delay offset relative to the input. All five taps are equally spaced in time, with delay variation tightly coupled across temperature and supply voltage (e.g., if TAP1 slows, all taps slow proportionally).

It operates strictly as a unidirectional signal repeater: input logic state is reproduced at each tap after its fixed delay, with no internal buffering, level-shifting, or edge regeneration. Timing is measured at 1.5V thresholds for both rising (t_PLH) and falling (t_PHL) edges, and specified under 5V ±5% supply with load matching one 74F04 input gate.

FAQ

What is the nominal delay of each tap in DS1100Z-30/T&R?

The DS1100Z-30/T&R provides five equally spaced nominal delays: TAP 1 = 6ns, TAP 2 = 12ns, TAP 3 = 18ns, TAP 4 = 24ns, and TAP 5 = 30ns. These values are specified at +25°C and 5V, with ±4ns tolerance over the full -40°C to +85°C industrial temperature range. Each tap reproduces the input logic state after its respective fixed delay, preserving both leading and trailing edge timing.

Is DS1100Z-30/T&R compatible with 3.3V logic systems?

No, DS1100Z-30/T&R is specified only for 5V operation (4.75V to 5.25V). Its input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive characteristics are designed for TTL/CMOS 5V logic families. Direct interfacing with 3.3V systems requires level translation; using DS1100Z-30/T&R outside its rated supply violates absolute maximum ratings and invalidates timing specifications.

Can DS1100Z-30/T&R drive more than 10 × 74LS loads per tap?

No - DS1100Z-30/T&R is characterized to drive up to 10 × 74LS loads per tap under datasheet conditions (VCC = min, VOL = 0.5V, IOL = 12mA). Exceeding this load increases propagation delay uncertainty, degrades edge fidelity, and may violate output voltage specifications. For heavier loads, external buffer amplification is required to maintain DS1100Z-30/T&R's specified timing accuracy.

Does DS1100Z-30/T&R require external decoupling capacitors?

Yes - DS1100Z-30/T&R requires a minimum 0.1μF ceramic decoupling capacitor placed as close as possible to the VCC and GND pins. This is essential to suppress supply noise that directly modulates delay accuracy. The datasheet specifies active current (ICC) measurement with outputs open and assumes proper local decoupling; omitting it causes increased delay variation and potential timing failure in noise-sensitive applications.

What does the "/T&R" suffix mean in DS1100Z-30/T&R?

The "/T&R" suffix in DS1100Z-30/T&R indicates tape-and-reel packaging - a standard carrier format for automated SMT placement. It denotes that the device is supplied in a continuous plastic carrier tape wound on a reel, with 2,500 units per reel for the 8-pin SO package. This format ensures consistent feeding, ESD-safe handling, and compatibility with high-volume pick-and-place equipment used in electronics manufacturing.
