Analog Devices Inc./Maxim Integrated DS1013H-30

Overview

DS1013H-30 from Maxim Integrated (formerly Dallas Semiconductor) is a 3-channel all-silicon logic delay line in an 8-pin PDIP package, delivering precise 30 ns fixed delay on each of three independent buffered outputs with ±2 ns tolerance over 0°C to +70°C and 4.75 V–5.25 V supply. It reproduces both rising and falling edges with equal accuracy and drives up to 10 LS-TTL loads-used in digital timing alignment, clock skew correction, and pulse-width stabilization in test equipment and industrial control systems.

For engineers reviewing the DS1013H-30 datasheet, DS1013H-30 pinout, DS1013H-30 application, or DS1013H-30 equivalent, key selection considerations include its guaranteed 30 ns per-output delay tolerance, TTL/CMOS compatibility, low-power CMOS operation, 8-pin DIP footprint, and edge-aligned timing performance across voltage and temperature variations.

Technical Context

The DS1013H-30 implements three identical, independent buffered delay paths within a single monolithic CMOS IC, each replicating input logic state after a fixed 30 ns propagation delay measured at the 1.5 V threshold for both t_PLH and t_PHL. Its architecture ensures unidirectional delay drift-i.e., all outputs slow or speed together under temperature/voltage variation-enabling predictable inter-channel skew behavior.

Designed for logic-level signal conditioning, it operates strictly at 5 V ±5%, accepts standard TTL/CMOS input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.2 V), and maintains output drive capability (I_OL = 12 mA, I_OH = –1 mA) while consuming 40–70 mA active current-making it suitable for high-fanout, noise-immune timing insertion without external buffering.

Key Specifications

Pinout & Package

DS1013H-30 is housed in an 8-pin plastic dual in-line package (PDIP), 300-mil width, with pin 1 marked by notch or dot. Pin assignments are standardized per Dallas Semiconductor mechanical drawing 56-G5005-000A (P8-9 variant).

Manufacturer

Maxim Integrated (acquired Dallas Semiconductor in 2001) is a U.S.-based analog and mixed-signal semiconductor company focused on high-reliability, precision timing, power, and interface solutions.

The DS1013 series was developed by Dallas Semiconductor to replace aging hybrid delay modules with monolithic silicon alternatives-targeting industrial test systems, telecom infrastructure, and military-grade digital instrumentation where timing repeatability and long-term stability are critical.

FAQ

What is the guaranteed delay tolerance for DS1013H-30 across temperature and voltage?

The DS1013H-30 guarantees ±2 ns delay tolerance for all three outputs over the full operating range of 0°C to +70°C and supply voltage 4.75 V to 5.25 V. This specification holds for both t_PLH and t_PHL, with unidirectional drift meaning all outputs shift together-preserving inter-channel skew. Measurements are referenced to the 1.5 V logic threshold.

Can DS1013H-30 drive standard TTL loads directly?

Yes, DS1013H-30 can drive up to 10 × 74LS loads per output, with I_OL = 12 mA and I_OH = –1 mA specified at V_CC = 4.75 V. Its buffered outputs provide sufficient current and voltage swing to meet TTL input thresholds without external drivers-verified under standard test conditions using one 74F04-equivalent load per output.

Is DS1013H-30 RoHS compliant?

No, DS1013H-30 is not RoHS compliant-it uses leaded solder finish and non-RoHS materials per its product status in the Maxim/Dallas database. For RoHS-compliant equivalents, consider DS1013M-30 (same 8-pin PDIP, lead-free) or DS1013-30+ (14-pin PDIP, lead-free), both offering identical 30 ns delay performance.

How does DS1013H-30 handle input pulse width and rise/fall time?

DS1013H-30 requires input pulse width ≥100% of t_PLH (i.e., ≥30 ns) and rise/fall times ≤3 ns to ensure accurate 1.5 V threshold crossing detection. Shorter pulses or slower edges may cause timing uncertainty or missed transitions. The device's internal logic is optimized for clean, fast-edged signals typical of TTL/CMOS sources.

What is the maximum output short-circuit duration allowed for DS1013H-30?

The absolute maximum rating for DS1013H-30 specifies 50 mA short-circuit output current for up to 1 second. Exceeding this limit-even briefly-may cause permanent damage. System design must include current-limiting resistors or fault protection if outputs could be inadvertently shorted to V_CC or GND during operation or testing.
