Analog Devices Inc./Maxim Integrated DS1010G-50

Overview

DS1010G-50 from Maxim Integrated (formerly Dallas Semiconductor) is a 10-tap all-silicon delay line IC with fixed 50 ns total delay (5 ns per tap), TTL/CMOS-compatible input/output, and ±5% or ±2 ns delay tolerance. It operates at 5 V, supports leading and trailing edge accuracy, and drives up to ten 74LS loads per tap in industrial timing, pulse shaping, and clock deskew applications.

For engineers reviewing the DS1010G-50 datasheet, DS1010G-50 pinout, DS1010G-50 application, or DS1010G-50 equivalent, this device serves as a drop-in replacement for hybrid delay lines in DIP-14 footprint designs requiring stable, low-power, edge-accurate time delays without external components.

Technical Context

The DS1010G-50 implements a monolithic CMOS silicon delay chain with ten equally spaced taps, where TAP 10 delivers the full 50 ns delay with matched tPLH and tPHL propagation times. Delay accuracy is specified over 0°C to +70°C with unidirectional temperature drift behavior across all taps.

It features a 5 V supply interface, 50 Ω input source impedance compatibility, 1.5 V switching threshold for timing measurements, and supports wave, IR, and vapor-phase soldering. The device exhibits no internal feedback or programmability-delay is purely fixed and deterministic.

Manufacturer

Maxim Integrated (acquired Dallas Semiconductor in 2001) designs precision analog and mixed-signal ICs for industrial, communications, and computing applications.

The DS1010 series was developed as a silicon-based replacement for hybrid delay lines, targeting cost-sensitive, high-reliability timing functions in commercial-grade digital systems.

FAQ

What is the total propagation delay of DS1010G-50 from input to TAP 10?

The DS1010G-50 delivers a fixed total delay of 50 ns from the IN pin to the TAP 10 output, with ±5% or ±2 ns tolerance. This value is defined by the dash-number suffix and verified under standard test conditions (VCC = 5.0 V, TA = 25°C). Each intermediate tap provides an incrementally delayed copy: TAP 1 = 5 ns, TAP 2 = 10 ns, etc.

Is DS1010G-50 pin-compatible with older hybrid delay line modules?

Yes, DS1010G-50 uses a standard 14-pin DIP package (300-mil width) with pinout matching legacy hybrid delay lines. Pin 1 is IN, pins 3–14 carry TAP outputs and power/ground as specified in the mechanical drawing 56-G5005-001A. No PCB layout changes are needed for direct replacement in existing sockets or footprints.

Does DS1010G-50 support both rising and falling edge delay accuracy?

Yes, DS1010G-50 guarantees matched tPLH (rising edge) and tPHL (falling edge) delays across all taps, with identical ±5% or ±2 ns tolerance on both transitions. This enables faithful reproduction of input pulse width and duty cycle at any tap output-critical for clock deskew and pulse shaping.

What is the maximum capacitive load DS1010G-50 can drive per tap?

Each tap of DS1010G-50 is rated to drive up to ten 74LS-type logic inputs, corresponding to approximately 10 × 20 pF = 200 pF total load capacitance. Driving heavier loads may degrade edge rate and delay accuracy; for >200 pF, buffer amplification is recommended before connecting to downstream logic.

Can DS1010G-50 operate outside the 0°C to +70°C range?

No-DS1010G-50 is characterized and guaranteed only for operation between 0°C and +70°C. While storage temperature extends to -55°C to +125°C, functional performance (especially delay accuracy and output drive) is not assured outside the specified commercial temperature range. For extended temperature use, consult Maxim's DS1010L series or alternative qualified parts.
