TS864AIN

Overview

The TS864AIN is a rail-to-rail micropower BiCMOS quad comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 2.7 V to 10 V and supports an operating temperature range from -40 °C to +85 °C. The device features four differential comparators with push-pull outputs, consuming only 6 μA per comparator at 2.7 V. It exhibits a response time of 500 ns at 2.7 V for a 100 mV overdrive and includes ESD protection rated at 2 kV.

Feature Summary

• Rail-to-rail CMOS inputs enable full signal swing compatibility across the supply range.
• Push-pull output structure allows direct connection to microcontrollers without external pull-up resistors.
• Ultra-low current consumption optimizes performance in battery-powered systems.

Applications

• Battery-powered portable electronic devices
• Microcontroller interface circuits
• Threshold detection systems

Procurement Notes

Verify the specific suffix 'AIN' against official STMicroelectronics documentation to confirm pinout, package type, and electrical tolerances. Ensure the component matches the required SO-14 or TSSOP-14 form factor and that the industrial temperature grade aligns with system constraints. Cross-reference ordering codes with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when low power consumption is critical alongside high-speed switching capabilities. The rail-to-rail input capability simplifies circuit design by eliminating level-shifting requirements. Verify that the 5 mA output drive current meets the load requirements of the connected digital logic or microcontroller inputs.

Part Context

The TS864AIN belongs to the TS86x family, which includes single, dual, and quad comparator variants. This family is characterized by its BiCMOS technology, offering a balance between speed and power efficiency. The quad configuration provides multiple independent comparison channels in a compact footprint, suitable for space-constrained designs.

Replacement Considerations

Compatible substitutes include other members of the TS86x family such as TS864IDT or TS864IPT, provided the package type (SOIC-14 vs TSSOP-14) and suffix specifications match the board layout and thermal requirements.
