TS861AID

Overview

The TS861AID is a single-channel analog comparator from the TS86x series, manufactured by STMicroelectronics. It utilizes rail-to-rail micropower BiCMOS technology and operates within a supply voltage range of 2.7 V to 10 V. The device features push-pull outputs and supports an operating temperature range from -40 °C to +85 °C. Key electrical parameters include a propagation delay of 2 µs maximum, input offset voltage of 7 mV maximum at 5 V, and input bias current of 300 pA maximum at 5 V. It is housed in a standard 8-DIP package with a width of 0.300 inches (7.62 mm).

Feature Summary

• Rail-to-rail CMOS inputs allow signal detection across the full supply voltage range.
• Push-pull output stage provides direct interfacing with digital logic without requiring external pull-up resistors.
• Ultra-low current consumption enables efficient operation in battery-powered applications.
• Integrated ESD protection and latch-up immunity ensure robust performance in harsh environments.

Applications

• Battery-powered instrumentation systems
• Temperature monitoring circuits
• Voltage level sensing interfaces

Procurement Notes

Verify the specific suffix 'D' confirms the 8-DIP through-hole package configuration. Confirm RoHS compliance status for the specific manufacturing batch. Ensure the component meets the required thermal dissipation specifications for the intended enclosure environment.

Selection Notes

Select this component when a single comparator with rail-to-rail input capability is required in a DIP package. Consider alternative packages such as SOT-23-5 or SOIC if board space constraints necessitate surface-mount technologies. Verify that the 2 µs propagation delay meets the timing requirements of the target application.

Part Context

The TS861AID belongs to the TS86x family, which includes single, dual, and quad comparator variants. This family is characterized by high speed-to-power ratios and low voltage operation. The TS861 specifically denotes the single-channel version of this micropower BiCMOS comparator series.

Replacement Considerations

Compatible alternatives include the TS861AIN and TS861AIDT. Verify pinout compatibility and package dimensions before substitution. Ensure electrical parameters such as propagation delay and input offset voltage meet design requirements.
