DS1045S-4

Overview

The DS1045S-4 is a programmable silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It features one input and two 4-bit programmable delay outputs, allowing for 16 selectable delay values per output. The device provides uniform delay increments of 4 ns, with a minimum inherent delay of 9 ns and a maximum achievable delay of 84 ns. It operates on a single 5V supply (4.75V to 5.25V) and utilizes low-power CMOS technology compatible with TTL levels. The component is housed in a 16-pin SOIC surface-mount package.

Feature Summary

• Dual 4-bit programmable outputs derived from a single input signal
• Programmable via four dedicated input pins for flexible configuration
• Accurate reproduction of input pulses with leading and trailing edge precision

Applications

• Timing adjustment in digital communication systems
• Pulse width modulation circuitry
• Clock skew compensation in high-speed data interfaces

Procurement Notes

Verify the current lifecycle status as the DS1045 series may be discontinued or restricted. Confirm availability through authorized distributors and check for RoHS compliance documentation specific to the manufacturing date code before procurement planning.

Selection Notes

Select the DS1045S-4 specifically when a 4 ns delay increment is required. Compare against the DS1045S-3 (3 ns) and DS1045S-5 (5 ns) variants to ensure the timing resolution matches the system requirements. Ensure the 16-pin SOIC package fits the PCB layout constraints.

Part Context

The DS1045S-4 belongs to the DS1045 family of all-silicon programmable delay lines. This family includes variants with 3 ns, 4 ns, and 5 ns increments. The 'S' suffix denotes the SOIC surface-mount package, distinguishing it from the DIP version. These components are designed for applications requiring precise, adjustable time delays without external discrete components.

Replacement Considerations

Direct replacements within the same family include the DS1045S-3 and DS1045S-5 if different delay increments are acceptable. Verify pinout compatibility and electrical specifications before substituting.
