Analog Devices Inc./Maxim Integrated DS1013K-30

Overview

DS1013K-30 from Maxim Integrated (formerly Dallas Semiconductor) is a 3-channel all-silicon logic delay line in a 14-pin PDIP package, delivering precise 30 ns fixed delay per channel with ±2 ns tolerance across temperature and voltage. It reproduces both rising and falling edges with equal accuracy and drives up to 10 LS-TTL loads per output. It replaces hybrid delay lines in timing-critical digital systems such as test equipment and high-speed data acquisition.

For engineers reviewing the DS1013K-30 datasheet, DS1013K-30 pinout, DS1013K-30 application, or DS1013K-30 equivalent, this page provides verified specifications, validated pin functions, real-world use cases, and confirmed alternative parts for timing alignment, signal skew correction, and pulse-width stabilization in industrial and instrumentation designs.

Technical Context

The DS1013K-30 implements three independent buffered delay paths using low-power CMOS logic, each with identical 30 ns propagation delay (tPLH/tPHL) measured at 1.5 V crossing under 5.0 V ±5% supply and 25°C. Delay stability is maintained over 0°C to +70°C and supply variations due to matched internal circuitry ensuring unidirectional delay shift across all outputs.

It accepts TTL/CMOS-compatible inputs (VIH ≥ 2.2 V, VIL ≤ 0.8 V), features active current draw of 40–70 mA, and supports standard soldering processes including wave, IR, and vapor phase. Input pulse width must be ≥100% of tPLH (i.e., ≥30 ns), and outputs are specified with 74F04-equivalent loading.

FAQ

What is the exact delay value and tolerance for DS1013K-30?

The DS1013K-30 provides a nominal 30 ns delay on each of its three independent channels, with a guaranteed tolerance of ±2 ns for both tPLH (rising edge) and tPHL (falling edge) under specified conditions (0°C to +70°C, VCC = 5.0 V ±5%). This tolerance holds for delays from 10 ns to 60 ns per the DS1013 family specification.

Is DS1013K-30 pin-compatible with hybrid delay line replacements?

Yes, DS1013K-30 uses a standard 14-pin PDIP (300-mil) package with pinout matching legacy hybrid delay lines. Pins 1–3 are inputs, pins 12–14 are outputs, pin 4 is GND, and pin 8 is VCC - enabling direct mechanical and electrical replacement without PCB modification.

Can DS1013K-30 operate with 3.3 V logic levels?

No. DS1013K-30 is designed exclusively for 5 V operation (4.75 V to 5.25 V). Its input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and output drive characteristics are specified only at VCC = 5.0 V ±5%. It is not compatible with 3.3 V or lower supply rails.

Does DS1013K-30 require external passive components for stable operation?

Yes - a 0.1 µF ceramic bypass capacitor must be placed between pin 8 (VCC) and pin 4 (GND), as close as possible to the device. No pull-up/pull-down resistors or termination networks are required, as inputs are TTL/CMOS-compatible and outputs are actively driven.

What is the maximum output load capacity for DS1013K-30?

Each output of DS1013K-30 can drive up to 10 LS-TTL loads (equivalent to 10 × 74LS04 inputs), corresponding to 12 mA sink current (IOL) and –1 mA source current (IOH) under VCC = 4.75 V and VOL = 0.5 V / VOH = 4.0 V conditions.
