DS1110LE-500+T&R

Delay Lines IC Overview

The DS1110LE-500+T&R is a 3V, 10-tap silicon delay line from the DS1110L series. It provides delays ranging from 10ns to 500ns with nominal accuracy of ±5% or ±2ns at 3.3V and +25°C. The device operates on a supply voltage between 2.7V and 3.6V. It features equally spaced taps, low-power CMOS technology, and TTL/CMOS compatibility. Packaged in a 14-pin TSSOP, it supports both leading- and trailing-edge delays with equal precision.

Delay Lines IC Feature Summary

• All-silicon design providing stable and precise delays across commercial and industrial temperature ranges
• Low-profile 14-pin TSSOP package suitable for automated insertion and vapor phase or IR soldering
• Capable of driving up to ten 74LS-type loads per tap output

Delay Lines IC Applications

• Communications Equipment
• Medical Devices
• Automated Test Equipment
• PC Peripheral Devices

Delay Lines IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for lead-free markings on the package. Ensure storage conditions adhere to moisture sensitivity level requirements before reflow soldering.

Delay Lines IC Selection Notes

Select this part when a fixed 500ns total delay is required within a 3V logic system. Compare against the standard 5V DS1110E if operating voltage differs. Verify that the 14-pin TSSOP footprint matches the PCB layout constraints and thermal management needs.

Delay Lines IC Part Context

This component belongs to the DS1110L family, which serves as the 3V version of the DS1110 series. It maintains functional equivalence regarding tap spacing and drive capability while adapting to lower voltage operation. The 'LE' suffix indicates the specific delay value and tape-and-reel packaging format.
