Overview
The LM393FVT-E2 is a dual-channel ground-sense analog comparator manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 32 V and features an open collector output capable of sourcing up to 16 mA. The device exhibits a typical response time of 1 µs, a maximum input offset voltage of 4.5 mV, and a typical input bias current of 50 nA. It functions across an operating temperature range from -40 °C to 85 °C and is housed in a TSSOP-B8 package with dimensions of 3.0x6.4 mm.
Feature Summary
- Ground-sensed input and output capability for single-supply operation
- Open collector output structure compatible with various logic families
- Wide operating supply voltage range supporting diverse power environments
Applications
- Limit comparators
- Simple analog-to-digital converters
- Pulse and squarewave generators
- Time delay generators
- High voltage digital logic gates
Procurement Notes
Verify the specific suffix E2 against the latest manufacturer documentation to confirm RoHS compliance status and exact pinout configuration. Confirm that the TSSOP-B8 package matches the target PCB footprint requirements. Ensure the open collector output interface aligns with the system's pull-up resistor strategy. Validate that the operating temperature range meets the environmental constraints of the final assembly.
Selection Notes
Select this component when ground-referenced signal sensing is required within a wide single-supply voltage window. The low input offset voltage supports precision threshold detection applications. The open collector output allows flexible interfacing with different logic voltage levels. Verify that the 1 µs response time satisfies the speed requirements of the intended circuit design.
Part Context
This part belongs to the LM393 series of dual independent precision voltage comparators designed for single or split supply operation. The series is characterized by low power supply current drain independent of voltage magnitude. The input common-mode voltage range includes ground, enabling direct sensing near the negative rail without requiring dual supplies.
Replacement Considerations
