SST403 SOIC 8L-TR

Overview

The SST403 is a high-speed, low-power quad comparator manufactured by Linear Integrated Systems, Inc. It operates from a single supply voltage ranging from 2.7V to 12V or dual supplies up to ±6V. The device features a typical propagation delay of 25ns and a response time of 10ns. It offers a high slew rate of 0.7V/µs and can drive loads up to 50pF. The output stage is compatible with TTL, CMOS, and MOS logic families, providing a high-level output current of 16mA and a low-level sink current of 32mA. It is housed in an 8-lead SOIC package.

Feature Summary

• Quad configuration integrating four independent comparators within a single compact package
• High-speed operation with fast propagation delay and response times for signal processing
• Wide single or dual power supply compatibility ensuring flexibility in various circuit designs
• TTL and CMOS logic output compatibility allowing direct interfacing with standard digital systems

Applications

Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems, Inc., noting that this entity was acquired by Analog Devices. Confirm the specific suffix TR indicates tape and reel packaging if required for automated assembly. Ensure the package type matches the 8-lead SOIC specification. Cross-reference datasheets for exact electrical limits against the specific revision available from authorized distributors.

Selection Notes

Select this component when a quad comparator solution is needed to save board space compared to using individual units. It is suitable for applications requiring moderate speed and wide supply voltage ranges. Consider the output drive capability for direct logic interfacing without additional buffering. Evaluate thermal performance if operating near maximum supply voltages in enclosed environments.
