TS864ID

Overview

The TS864ID is a rail-to-rail micropower BiCMOS quad comparator from STMicroelectronics, characterized for operation between 2.7 V and 10 V over -40 °C to +85 °C. It features ultra-low current consumption of 6 μA per comparator at 2.7 V and a response time of 500 ns at 2.7 V for a 100 mV overdrive. The device includes push-pull outputs for direct microcontroller connection without pull-up resistors, ESD protection rated at 2 kV, and Class A latch-up immunity.

Feature Summary

• Rail-to-rail CMOS inputs enable full supply range signal handling.
• Push-pull output stage allows direct interface with digital logic.
• Ultra-low power consumption optimizes battery life in portable systems.

Applications

• Battery-powered consumer electronics
• Portable measurement instruments
• Low-power signal conditioning circuits

Procurement Notes

Verify the specific package suffix (e.g., ID vs IPT) against the datasheet to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status and check for end-of-life notices on distributor platforms before finalizing procurement plans.

Selection Notes

Select this component when low quiescent current and wide input common-mode range are critical. Ensure the application voltage stays within the 2.7 V to 10 V limit. Consider the TSSOP or SO-8 packages if space constraints allow, as they offer better thermal performance than smaller alternatives.

Part Context

This part belongs to the TS86x family, which includes single (TS861), dual (TS862), and quad (TS864) variants. All members share identical electrical characteristics and pinouts where applicable, allowing for design flexibility across different channel requirements while maintaining consistent performance metrics.

Replacement Considerations

Direct substitutes include TS864IPT and TS864IPTTR. Verify package compatibility and ensure the replacement maintains the same rail-to-rail input/output specifications and operating temperature range.
