TS862AID

Overview

The TS862AID is a dual rail-to-rail micropower BiCMOS comparator manufactured by STMicroelectronics. It operates from a single supply voltage ranging from 2.7 V to 10 V. The device features two independent channels with push-pull outputs, each capable of sourcing or sinking up to 5 mA. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V and a typical quiescent current consumption of 6 µA per channel. The propagation delay is typically 2 µs. It functions within an industrial temperature range of -40°C to +85°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Rail-to-rail output capability allows operation with low-voltage digital logic interfaces without level shifting requirements.
• Micropower BiCMOS technology ensures minimal energy consumption, making it suitable for battery-powered applications.
• General-purpose design provides robust performance across varying load conditions with standard push-pull output stages.

Applications

• Industrial control systems requiring precise signal threshold detection
• Battery-operated devices where low power consumption is critical
• Voltage monitoring circuits for power management applications

Procurement Notes

Verify the specific suffix 'AID' corresponds to the 8-SOIC package and industrial temperature grade (-40°C to +85°C). Confirm that the 7 mV input offset voltage specification applies to your operating voltage, as parameters may vary with supply changes. Ensure compatibility with your PCB footprint for the SOIC-8 package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel comparator with rail-to-rail output is required for low-power designs. It is appropriate for applications needing moderate speed (2 µs delay) rather than high-speed switching. Consider the 7 mV offset voltage limit if high precision is necessary at 5 V operation. Verify that the 5 mA output drive current meets the load requirements of the connected circuitry.

Part Context

The TS862AID belongs to the TS862 family of rail-to-rail micropower BiCMOS comparators. This series is designed to replace older bipolar comparators in modern low-voltage systems. The 'AID' designation specifically identifies the industrial temperature range variant packaged in an 8-pin Small Outline Integrated Circuit (SOIC) format, distinguishing it from other package options like TSSOP.

Replacement Considerations

Check datasheets for alternative dual comparators with similar 2.7 V to 10 V operating ranges and rail-to-rail outputs. Verify pinout compatibility with the 8-SOIC package to ensure direct replacement feasibility without PCB redesign. Compare propagation delay and offset voltage specifications to confirm functional equivalence in the target application.
