TS864IN

Overview

The TS864IN 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 independent channels 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.
• Push-pull output stage allows direct connection to microcontrollers without external pull-up resistors.
• Ultra-low current consumption optimizes battery life in portable systems.
• Integrated ESD protection ensures robustness against electrostatic discharge events.

Applications

• Battery-powered consumer electronics
• Portable measurement instruments
• Microcontroller interface circuits

Procurement Notes

Verify the package type matches the required footprint, as the TS864 series is available in multiple configurations including SOIC-14 and TSSOP-14. Confirm that the specific suffix indicates the correct packaging format for automated assembly or manual placement needs. Ensure the component meets RoHS compliance requirements for the target market.

Selection Notes

Select this component when low power consumption is critical alongside high-speed comparison capabilities. The push-pull output simplifies circuit design by eliminating the need for external pull-up components. Consider the rail-to-rail input capability if the signal source does not reach the supply rails. Verify thermal performance within the specified operating temperature range.

Part Context

The TS864IN belongs to the TS86x family of comparators, which includes single, dual, and quad variants. This family is characterized by its excellent speed-to-power ratio and availability in compact packages such as SOT23-5, SO-8, SO-14, TSSOP8, and TSSOP14. The quad configuration provides four independent comparators in a single package, maximizing board space efficiency.

Replacement Considerations

Compatible alternatives include other quad rail-to-rail comparators with similar supply voltage ranges and low quiescent current specifications. Verify pinout compatibility and electrical parameters such as propagation delay and input offset voltage before substitution.
