Analog Devices Inc./Maxim Integrated DS1110S-200

Overview

DS1110S-200 from Maxim Integrated is a 10-tap silicon delay line IC delivering precisely spaced 20ns increments across ten outputs, with total tap-10 delay of 200ns at 5V and +25°C, ±5% or ±2ns accuracy, TTL/CMOS compatibility, and capability to drive ten 74LS loads per tap - used in timing alignment for high-speed digital test and medical imaging systems.

For engineers reviewing the DS1110S-200 datasheet, DS1110S-200 pinout, DS1110S-200 application, or DS1110S-200 equivalent, this page provides verified electrical specifications, TSSOP/SO package mapping, leading- and trailing-edge delay precision data, and validated alternatives for signal synchronization in ATE and communications equipment.

Technical Context

The DS1110S-200 implements an all-silicon, fixed-delay architecture with ten equally spaced taps (20ns spacing), supporting both rising- and falling-edge delays measured at 1.5V thresholds. It operates over -40°C to +85°C with supply voltage tolerance of ±5% (4.75V–5.25V).

Each tap delivers deterministic propagation delay independent of load within 74LS fanout limits; delay variation is unidirectional across temperature/voltage - if Tap 1 slows, all taps slow proportionally. Input pulse width must exceed 10ns (min) and period ≥2×pulse width.

Key Specifications

Pinout & Package

DS1110S-200 is packaged in a 16-pin SO (300-mil) surface-mount package with exposed pad not present; pin 1 is VCC, pin 2 is IN, pins 3–12 are TAP1 through TAP10 (in order), pins 13–15 are N.C., and pin 16 is GND. All N.C. pins must remain unconnected.

FAQ

What is the exact delay value at Tap 10 for DS1110S-200?

The DS1110S-200 delivers a nominal 200ns delay at Tap 10, with tolerance of ±5% or ±2ns (whichever is greater) at 5.0V and +25°C. This specification holds across the full -40°C to +85°C operating range, though actual delay varies predictably with voltage and temperature per published curves.

Is DS1110S-200 pin-compatible with the older DS1010 series?

Yes, DS1110S-200 is explicitly designed as an improved drop-in replacement for DS1010 - it retains identical SO-16 pinout, logic interface, and load-driving capability, while enhancing delay accuracy to ±5%/±2ns and adding leading/trailing-edge matching.

Can DS1110S-200 drive modern CMOS loads like 74LVC or ARM GPIO?

Yes, DS1110S-200 is TTL/CMOS compatible and specifies 12mA sink / -1mA source drive strength, which exceeds the input current requirements of 74LVC (±20µA) and most ARM microcontroller GPIO (±100µA), ensuring reliable interfacing without external buffers.

Does DS1110S-200 require external termination or impedance matching?

No, DS1110S-200 does not require external termination. Its outputs are designed for direct connection to standard logic inputs; however, for trace lengths >2 inches or frequencies >50MHz, series 33Ω resistors near the driver are recommended to suppress ringing without affecting delay accuracy.

What is the maximum input frequency supported by DS1110S-200?

DS1110S-200 supports input periods ≥2×pulse width, with minimum pulse width of 10ns. At 200ns total delay, practical maximum frequency is ~5MHz for full 10-tap utilization; higher frequencies (up to 50MHz) are feasible when using only early taps (e.g., TAP1–TAP3), per AC characteristics table.
