DS1100Z-125/T&R

Delay Lines IC Overview

The DS1100Z-125/T&R is a five-tap silicon delay line from the DS1100 series, manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced timing taps with a nominal total delay of 125ns across five stages (Tap 1: 25ns, Tap 2: 50ns, Tap 3: 75ns, Tap 4: 100ns, Tap 5: 125ns). The device operates on a single +5V supply within a voltage range of 4.75V to 5.25V and functions reliably in temperatures from -40°C to +85°C. Packaged in an 8-pin SOIC surface-mount format, it features TTL/CMOS-compatible inputs and outputs capable of driving up to 10 LS loads per tap.

Delay Lines IC Procurement Notes

Verify the specific ordering suffix to confirm package type and reel configuration. The 'T&R' suffix indicates tape and reel packaging, while the 'Z' denotes the SOIC package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement.

Delay Lines IC Selection Notes

Select this component when a fixed 125ns total delay with intermediate tap points is required. Ensure the application supports 5V logic levels and operates within the specified industrial temperature range. Consider the SOIC footprint constraints during PCB layout design.

Delay Lines IC Part Context

This part belongs to the DS1100 family of economy timing elements. It serves as an improved replacement for the older DS1000 series, offering superior reliability through monolithic silicon construction compared to hybrid alternatives. The series includes various delay values ranging from 4ns to 500ns.

Delay Lines IC Replacement Considerations

The datasheet identifies the DS1100 as an improved replacement for the DS1000 series. Verify pinout compatibility and electrical characteristics against legacy components before substitution.

Delay Lines IC FAQ

How are the delay tolerances specified for the DS1100Z-125?

For delays greater than 40ns, such as the 125ns model, the tolerance is specified as a percentage of the nominal delay value rather than a fixed nanosecond amount.

What is the maximum input pulse width allowed?

The minimum input pulse width is specified as 20% of the Tap 5 delay time. For the DS1100Z-125, this equates to 25ns.

Can individual taps be disabled?

No, the device consists of a continuous silicon delay line where all five taps are active and equally spaced. Intermediate delay values are available only on a custom basis.
