Overview
The TS391SN2T1G is a single-channel general-purpose analog comparator manufactured by onsemi. It operates within a supply voltage range of 2 V to 36 V and draws a typical operating current of 500 uA. The device features an open collector output capable of sourcing 16 mA per channel. Key electrical specifications include a propagation delay of 850 ns, an input offset voltage of 9 mV, and an input bias current of 400 nA. It is housed in a surface-mount SOT-23-5 package and supports an extended operating temperature range from -40 C to +125 C.
Feature Summary
- Single-channel general-purpose analog comparator design
- Wide dual-supply operation capability from 2 V to 36 V
- Open collector output structure for flexible interfacing
Applications
- General purpose signal comparison circuits
- Voltage monitoring applications
- Threshold detection systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required RoHS compliance standards for the target market. Cross-reference the datasheet revision date with production records to validate manufacturing consistency. Confirm that the SOT-23-5 footprint matches the intended PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-power, single-channel comparator is required for general-purpose applications. The wide supply voltage range accommodates various system power rails without level shifting. The open collector output allows for wired-OR configurations and compatibility with different logic families. Consider the 850 ns response time for non-high-speed signaling needs.
Part Context
This part belongs to the TS391 series of analog comparators produced by onsemi. The series offers a balance of performance and power consumption suitable for consumer and industrial electronics. The TS391SN2T1G variant specifically utilizes the SOT-23-5 surface-mount package, providing a compact solution for space-constrained designs while maintaining standard comparator functionality.
Replacement Considerations
Direct substitutes may include other single-channel comparators in SOT-23-5 packages with similar supply voltage ranges and output types. Verify pinout compatibility and electrical parameters such as propagation delay and input offset voltage before substitution.
