TS862ID

Overview

The TS862ID is a dual analog comparator from the TS86x family, manufactured by STMicroelectronics. It utilizes MicroPwr BiCMOS technology and operates within a supply voltage range of 2.7 V to 10 V. The device features rail-to-rail CMOS inputs and push-pull outputs, eliminating the need for external pull-up resistors. Key electrical parameters include a quiescent current consumption of 6 μA per comparator at 2.7 V, a response time of 500 ns at 2.7 V with 100 mV overdrive, an input offset voltage (Vos) of 15 mV, and an input bias current (Ib) of 300 pA. Each channel provides an output current capability of 5 mA. The component is rated for operation between -40 °C and +85 °C and is housed in an SOIC-8 package.

Feature Summary

• Rail-to-rail CMOS inputs enable full signal swing compatibility across the supply range.
• Push-pull output stage allows direct interfacing with microcontrollers without additional pull-up components.
• Ultra-low power consumption of 6 μA per comparator supports extended battery life in portable systems.

Applications

• Battery-powered consumer electronics requiring low standby current
• Signal conditioning circuits in industrial monitoring systems
• Threshold detection interfaces for microcontroller-based embedded designs

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required SOIC-8 variant. Confirm temperature grade and RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when dual-channel comparison is required with minimal power draw. The push-pull output simplifies logic interface design compared to open-collector alternatives. Verify that the 15 mV offset voltage meets system accuracy requirements and that the 5 mA sink/source current suffices for the driven load impedance.

Part Context

This part belongs to the TS86x series, which includes single (TS861), dual (TS862), and quad (TS864) comparator variants. All members share identical electrical characteristics and pinout compatibility where applicable, differing only in channel count. The series is designed for cost-sensitive, space-constrained applications demanding high speed-to-power efficiency.

Replacement Considerations

Direct functional substitutes within the same family include TS861ID (single channel) and TS864ID (quad channel). Cross-family replacements require verification of pin compatibility, output drive strength, and offset voltage specifications against the original design constraints.
