Overview
The LMV331IDCKR is a single general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 5.5V and features an open-collector output capable of sourcing up to 84mA at 5V. The device exhibits a maximum propagation delay of 600ns and a maximum input offset voltage of 7mV at 5V. Input bias current is limited to 0.25µA at 5V, with a maximum quiescent current of 150µA. It is housed in a 5-SC70 package (SOT-353) and supports surface-mount installation across a temperature range of -40°C to 85°C.
Feature Summary
- Features an open-collector output interface compatible with various logic families
- Supports low-voltage single-supply operation from 2.7V to 5.5V
- Provides high output drive capability for direct interfacing
Applications
- General-purpose voltage threshold detection
- Level shifting between different logic domains
- Simple on/off control circuits
Procurement Notes
Verify the specific suffix IDCKR corresponds to the SC-70-5 package and tape-and-reel shipping format. Confirm RoHS compliance status and ensure the operating temperature range meets system requirements. Cross-reference manufacturer part numbers against distributor listings to avoid obsolete or alternate package variants.
Selection Notes
Select this component when a low-cost, single-channel comparator with moderate speed and high output drive is required. Consider the open-collector output limitation for pull-up resistor design. Evaluate if the 600ns propagation delay satisfies signal timing constraints compared to faster alternatives.
Part Context
This part belongs to the LMV331 family of low-voltage comparators. It shares functional similarities with other members like the LMV331M5 but differs in packaging. The IDCKR designation specifically identifies the SC-70-5 surface-mount variant produced by Texas Instruments.
Replacement Considerations
- LMV331M7X/NOPB
FAQ
