Analog Devices Inc./Maxim Integrated DS1100Z-20/T&R

Overview

DS1100Z-20/T&R from Maxim Integrated is a 5-tap silicon delay line with fixed tap delays of 4ns, 8ns, 12ns, 16ns, and 20ns; operates at 5V ±5%, supports -40°C to +85°C industrial temperature range, and drives up to 10 × 74LS loads per tap-used in digital timing alignment, pulse shaping, and clock skew compensation circuits.

For engineers reviewing the DS1100Z-20/T&R datasheet, DS1100Z-20/T&R pinout, DS1100Z-20/T&R application, or DS1100Z-20/T&R equivalent, key selection criteria include tap delay precision (±4ns over full temperature range), TTL/CMOS compatibility, SO-8 package footprint, and edge-aligned leading/trailing-edge reproduction for synchronous logic interfacing.

Technical Context

The DS1100Z-20/T&R 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 characteristics. Delay tolerance is specified as ±4ns (for ≤40ns delays) across -40°C to +85°C at 5V supply.

It functions as a passive timing element without internal clock generation or feedback control-input pulse width must exceed 20ns (per tWI specification), and output loading is defined per 74F04-equivalent gate capacitance. Power-up time is 200μs; active supply current is 30–50mA at 1MHz.

FAQ

What is the exact delay value for each tap of the DS1100Z-20/T&R?

The DS1100Z-20/T&R provides five fixed, equally spaced delays: TAP 1 = 4ns, TAP 2 = 8ns, TAP 3 = 12ns, TAP 4 = 16ns, and TAP 5 = 20ns - all measured at the 1.5V logic threshold under VCC = 5.0V and TA = -40°C to +85°C. These values are factory-trimmed and specified with ±4ns tolerance across the full operating range. Each tap reproduces both leading and trailing edges with identical delay.

Is the DS1100Z-20/T&R pin-compatible with other DS1100 variants?

Yes - all DS1100Z-xxx variants (including DS1100Z-20/T&R) share identical SO-8 pinout and electrical interface. The suffix "-20" only denotes the total delay of the final tap (20ns); internal tap spacing scales linearly (e.g., DS1100Z-100/T&R has taps at 20ns/40ns/60ns/80ns/100ns). No PCB redesign is needed when substituting between DS1100Z-xxx parts.

Can the DS1100Z-20/T&R drive modern CMOS loads like 74LVC or 74AUC?

Yes - the DS1100Z-20/T&R outputs are TTL/CMOS-compatible and can directly drive 74LVC and 74AUC inputs. Its output drive strength (12mA sink / -1mA source) exceeds the input current requirements of these families (<1μA leakage), and its 5V-tolerant inputs accept 3.3V logic levels. For best noise immunity, maintain proper VCC decoupling and minimize trace length to capacitive loads >20pF.

Does the DS1100Z-20/T&R require external components for basic operation?

No - the DS1100Z-20/T&R operates stand-alone with only VCC (4.75–5.25V), GND, and IN connected. A 0.1μF ceramic capacitor between VCC and GND near the package is strongly recommended for stable delay performance. No pull-ups, termination resistors, or configuration pins are needed. All timing behavior is intrinsic to the silicon delay structure.

What is the maximum input frequency supported by the DS1100Z-20/T&R?

The DS1100Z-20/T&R does not specify a maximum input frequency, but AC characterization assumes 1MHz operation (tWI ≥20ns). Input pulse width must exceed 20ns to ensure valid tap output generation. At higher frequencies, delay accuracy degrades due to layout-dependent factors (decoupling, trace inductance); for reliable operation above 5MHz, verify timing margins using actual board-level measurements with the DS1100Z-20/T&R in-circuit.
