LM393PWRG4

Overview

The LM393PWRG4 is a dual differential analog comparator manufactured by Texas Instruments, designed for surface-mount applications in SOIC-8 packages. It operates within a supply voltage range of 2 V to 30 V and draws a typical operating current of 2.5 mA. The device features a response time of 1.3 µs and an input offset voltage of 5 mV. With an input bias current of 50 nA, it supports CMOS and TTL output compatibility. The component functions across a temperature range of 0°C to +70°C without shutdown capabilities.

Feature Summary

• Dual-channel differential comparison architecture
• Wide single-supply voltage operation capability
• CMOS and TTL logic output interface compatibility

Applications

• General-purpose analog signal comparison
• Voltage monitoring circuits
• Over-voltage protection systems

Procurement Notes

Verify the specific package variant and manufacturer authenticity upon receipt. Confirm RoHS compliance status through official documentation. Check for end-of-life notices or production changes via Texas Instruments product change notifications. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Selection Notes

Select this component when dual independent comparators are required in a compact surface-mount form factor. Consider the 2 V to 30 V supply range for versatile power integration. Evaluate the 1.3 µs response time against system speed requirements. Verify that the SOIC-8 footprint aligns with existing PCB layout constraints.
