LMV393TP-SR

Overview

The LMV393TP-SR is a dual general-purpose comparator manufactured by 3PEAK. It operates on a supply voltage of 1.8V to 5.5V with a typical quiescent current of 40μA per channel. The device features an open-drain output, rail-to-rail input capability extending 200mV beyond the rails, and internal hysteresis for clean switching. Key electrical parameters include a maximum input offset voltage of ±3.5mV, typical propagation delays of 120ns (high-to-low) and 250ns (low-to-high), and an operating temperature range of -40°C to +85°C. It is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input operation allows sensing at ground or supply lines
• Internal hysteresis eliminates output switching due to noise
• Open-drain output provides maximum flexibility for logic level shifting
• No phase reversal occurs for overdriven inputs

Applications

• Peak and zero-crossing detectors
• Threshold detectors and discriminators
• Logic level shifting or translation
• Window comparators
• IR receivers

Procurement Notes

Verify the specific ordering suffix SR corresponds to the 8-pin SOIC package configuration as defined in the manufacturer's order information table. Confirm that the transport media requirements align with tape and reel specifications for the selected quantity. Ensure design compliance with absolute maximum ratings regarding supply voltage and input current limits to maintain device reliability.

Selection Notes

Select this component for applications requiring low-voltage single-supply operation with high-speed performance. The dual-channel architecture suits space-constrained designs needing two independent comparison functions. Consider the open-drain output requirement when designing pull-up resistor networks for the desired logic levels. Evaluate PCB layout guidelines to minimize surface leakage effects given the low input bias current characteristics.

Part Context

The LMV393TP-SR belongs to the LMV331-393 series of general-purpose comparators designed for portable consumer products. This series offers a cost-effective solution combining low power consumption with high speed. The LMV393 variant specifically provides two comparators in one package, contrasting with the single-channel LMV331 and quad-channel LMV339 options within the same family.

Replacement Considerations

LMV393TP-VR serves as a pin-compatible alternative utilizing an MSOP-8 package instead of SOIC-8.
