Analog Devices Inc./Maxim Integrated DS1110S-500/T&R

Overview

DS1110S-500/T&R from Maxim Integrated is a 10-tap silicon delay line IC delivering precisely spaced 50ns increments across 10 outputs, with total delay of 500ns at 5V and +25°C, ±5% or ±2ns tolerance, TTL/CMOS-compatible, and designed for leading- and trailing-edge timing alignment in high-speed digital synchronization circuits.

For engineers reviewing the DS1110S-500/T&R datasheet, DS1110S-500/T&R pinout, DS1110S-500/T&R application, or DS1110S-500/T&R equivalent, this page provides verified package mapping (16-pin SO), tap-specific delay accuracy, temperature/voltage stability data, load-driving capability (10 × 74LS), and confirmed drop-in replacement status versus DS1010.

Technical Context

The DS1110S-500/T&R implements an all-silicon, low-power CMOS delay architecture with fixed, monotonic tap spacing-each tap advances delay by exactly 50ns, and all taps track unidirectionally with temperature or supply voltage changes. It operates over -40°C to +85°C with 4.75V–5.25V supply range.

Delay measurement is referenced to 1.5V crossing points on input and output edges (tPLH/tPHL), supporting both rising- and falling-edge precision. Input pulse width must be ≥10% of Tap 10 delay (≥50ns), and minimum period is 2×pulse width or 20ns-whichever is greater.

Key Specifications

Pinout & Package

FAQ

What is the exact delay value at Tap 10 for DS1110S-500/T&R under nominal conditions?

The DS1110S-500/T&R delivers a nominal 500ns delay at Tap 10 when operated at +25°C and VCC = 5.0V. This value is specified in Table 1 of the datasheet and confirmed across all production lots. The DS1110S-500/T&R maintains this delay with ±5% or ±2ns tolerance-whichever is greater-under those conditions, and its monotonic tracking ensures all intermediate taps scale proportionally.

Does DS1110S-500/T&R support both rising- and falling-edge delay matching?

Yes, DS1110S-500/T&R is explicitly designed for equal precision on both edges: tPLH (rising) and tPHL (falling) delays are matched within specification across all 10 taps. The datasheet confirms this in the Features section ("Leading- and Trailing-Edge Accuracy") and AC Electrical Characteristics table, where both parameters share identical min/typ/max values under the same test conditions.

Can DS1110S-500/T&R drive standard TTL loads directly?

Yes, DS1110S-500/T&R can drive up to ten 74LS-type loads per tap without external buffering. Its IOL = 12mA (min) and IOH = -1mA (min) at VCC = 4.75V ensure sufficient current delivery for TTL-compatible thresholds. This capability is stated in the General Description and verified in the DC Electrical Characteristics table-making DS1110S-500/T&R suitable for direct interfacing in legacy logic systems.

Is DS1110S-500/T&R pin-compatible with the older DS1010 delay line?

Yes, DS1110S-500/T&R is documented as an improved, drop-in replacement for DS1010 in the Features and Detailed Description sections. Both share identical 16-pin SO pinout, supply voltage, logic thresholds, and functional behavior-requiring no PCB changes. The DS1110S-500/T&R improves upon DS1010 with tighter delay tolerance (±5% vs. older ±10%) and enhanced edge-matching performance.

What is the maximum operating frequency supported by DS1110S-500/T&R?

DS1110S-500/T&R does not specify a maximum clock frequency but defines minimum input period and pulse width constraints: period ≥ 2×tWI or 20ns (whichever greater), and tWI ≥ 10% of Tap 10 delay (i.e., ≥50ns). Thus, the practical upper limit is ~10MHz for reliable timing fidelity. This is derived from the AC Electrical Characteristics table and Figure 2 timing diagram-not from a rated "frequency" spec.
